Stony Brook Foundation Trustees Award Recipient

To encourage and support promising early career faculty, the University, through the Provost’s Office, provides research, scholarship and art-making funding opportunities. Five Stony Brook Foundation Trustees Faculty Awards of $20,000 each are competitively available to early career faculty. The awards recognize early-career faculty whose research, creative activities and scholarly achievements predict an exceptional trajectory.

Assistant Professor Shanshan Yao is a recipient of this award for her project, “Restoring Tactile Sensation and Feedback in Robot-Assisted Surgery." The goal of this project is to restore the underutilized haptic sensation during robotic-assisted minimally invasive surgery by instrumenting multi-DOF tactile sensors on the robot/patient side and multimodal haptic feedback interfaces on the surgeon side. The tactile sensors mounted to surgical tools will gather multi-DOF force and torque during the tool-tissue or tool-tool contact. The multimodal haptic actuators attached to the surgeon’s skin will enable the transmission of the sensed tactile information to the surgeon in real-time. The system is expected to improve operation accuracy, decrease operation duration, and enable more complicated surgical tasks without damaging tissues. Learn more here.

A practical Cooler with a unique design

Interim Chair and professor, Jon Longtin was quoted in the Wall Street Journal article "The Cooler That Keeps Food Cold and Prevents Soggy Sandwiches" about the new Ninja FrostVault cooler. The piece is an honest review of the product which is being described as "the year's most practical cooler that solves a long-standing problem," written by Sal Vaglica, Stony Brook alumni. The cooler's unique design includes a drawer, that without adding ice, keeps cooked and raw food dry and below 40 degrees fahrenheit. "Heat is removed by the ice chilled 'ceiling' of the lower container, which is also the bottom of the upper container, to keep the lower chamber chilled," says Longtin. "Heat leaks from the outside into the lower chamber which is then removed by the ceiling, establishing a steady temperature condition." Learn more here.

Advancing Endovascular Treatment: Personalized Device Design through Topology Optimization

Associate Professor Shikui Chen along with Dr. Chander Sandasvian (PI, SBU Hospital) and Professor David Gu (CS Department) were awarded an OVPR Seed Grant for their project "Advancing Endocascular Treatment: Personalized Device Design through Toplogy Optimization." This project aims to improve endovascular treatments for vascular diseases like brain aneurysms, aortic aneurysms, and cardiac valve replacements.

Current treatments Shikui Seed Grant 2024 face limitations due to the non-optimal fit of medical devices to patient anatomy, leading to complications like recanalization, endoleaks, and paravalvular leaks. The project proposes using advanced computational tools, particularly Topology Optimization (TO) and computational conformal mapping, to design personalized, patient-matched devices (PMDs).

These tools will help simulate deployable structures that conform accurately to individual patients' vascular anatomy, thereby enhancing treatment efficacy and reducing complications. The project's goal, supported by an OVPR seed grant, includes two main aims: generating patient-specific device designs and enabling effective transcatheter deployment using TO and conformal mapping.

Overcoming Carbon-Free Fuel Challenges: Laser-Induced Ammonia Combustion

Assistant Professor Dimitris Assanis and Co-PI, Associate Professor David Hwang were awarded an OVPR seed grant for their project "Overcoming Carbon-Fuel Challenges: Laser-Induced Ammonia Combustion." Ammonia is carbon-free fuel with great long duration storage capabilities that can be made from renewable energy and can help decarbonize the ~2B internal combustion piston engines in the world so we can meet our amb Assanis_Hwang_SeedGrant2024 itious net-zero carbon goals.

The problem is that Ammonia combustion is challenged by high ignition temperature requirements and slow flame speeds thus requires hydrogen addition or a new, innovative approach. Laser-induced decomposition and ignition can break the parent fuel, Ammonia, into more reactive intermediate kinetic species of NH2, NH and other radical species that are more readily ignitable and can achieve faster combustion propagation rates.

New Patent Issued 2023: System and Method of Characterizing the Equibiaxial Compressive Strength of 2D Woven Composites

Associate Professor Kedar Kirane and co-inventors, former MS students Daniel Deland and Zongyan Zhang were recently issued a patent. "This technology proposes a novel but simple idea that allows simple and reliable measurement of the equibiaxial compressive strength of 2D woven composites, by application of a uniaxial out of plane load, with a very simple specimen geometry and test set up. The testing method for this purpose is the ring on ring flexure test. In this test, the biaxial strength can be measured by subjecting un-notched disks or plates to a monotonic, out of plane load at the center. This produces biaxial flexure of the specimen and effectively converts a uniaxial load into a biaxial state of stress. This test set up is inexpensive and the specimen geometry is simple. It also does not require any expensive specimen grips."

Materials Failure of the Titan Submersible

After the June 18th Titan subermersible implosion, the New York Times looked for answers on how such a disaster could have happened. "Moisture or seas salt could have degraded the hull's carbon fiber and the glue joining it to the titanium, creating another potential weak point, said Associate Professor Kedar Kirane, a mechanical engineer with expertise in damage, fracture and fatigue in fiber-reinforced composites." See article here.

Spontaneous Emulsification Research Awarded NSF Grant

Professor Thomas Cubaud from the Mechanical Engineering Department has been awarded a NSF grant of $359,641 to study the dynamics of spontaneous emulsification in microfluidic systems. The project will examine the basic multiphase flow properties of mixtures made of oil, aqueous, and organic solvents at the small scale. The phenomenon of spontaneous emulsification refers to the natural formation of droplets due to the presence of a miscible solvent in oil-water systems and offers great opportunities for tailoring the properties of soft materials and developing innovative methods for the treatment of oil and aqueous products in a range of industries, including pharmaceutical, personal NSF Logo care, food, energy, and in the environment. While the multiphase flow behavior of pure substances is relatively well understood, less is known about the influence of fluid additives, such as alcohol solvents, which significantly alter material properties and multiphase flow arrangements. Alcohols compose an important class of simple organic compounds with a myriad of practical uses as extractants, antiseptics, detergents, biofuels, wetting agents, viscosity modifiers, or emulsifiers. Activities are designed to unravel the physics of multiphase flows in the presence of miscible solvents and develop new predictive knowledge into an array of captivating fluid phenomena of fundamental and practical interests.

Optimization for Electric Machine Design," which was prepared by a team consisting of colleagues from SBU and GE Renewable Energy. The SBU team includes Prof. Shikui Chen and Prof. Jon Longtin of the Mechanical Engineering Department, and Prof. Fang Luo of the Electrical and Computer Engineering Department. The total amount for this award is $550,000 for three years. General Electric Company (GE) is also sponsoring the project, under the award title "GE Renewable Energy Onshore Wind Project."

The collaborative team aims to advance the design of Rare-Earth (RE) permanent magnet structures for generator systems and improve the architecture and design methodology of future generators and electric motors. This project is expected to significantly increase the applicability of physics-based simulation-driven design technology to the growing volume of electrical engineering problems. The success of this project could change the landscape of the electric generator and electric motor industries.

The SBU-GE team will work closely to develop a Topology Optimization (TO) co-design/co-optimization software tool “Magnet Topology Optimization (MagneTOP)” for electric machine design. The software tool suite consists of a topology optimization engine and a general boundary condition generator. The team will demonstrate this software suite specifically in GE’s 15-Megawatt Haliade-X wind turbine generator, a Rare-Earth permanent magnet high-performance wind energy generator. The proposed software suite is expected to be a plug-in module that can be installed as an add-on to existing design and modeling tools such as Ansys®-EM Simulation, COMSOL, Abaqus, Autodesk-Fusion 360 and other industry standard CAD/CAE tools.

Through the technology development and commercialization of this TO software module, the SBU-GE team aims to reduce the reliance on RE materials in the design of high-performance generators and electric motors, thereby relieving the growing customer pains due to shortages, supply-chain issues, and increasing prices of RE materials.

Prof. Ladeinde Awarded SBU/BNL Seed Grant

Professor Foluso Ladeinde from the Mechanical Engineering department has been awarded a seed grant of $34,568 from the 2022 SBU BNL Seed Grant Program in order to develop a new approach to analyzing the unpredictable interactions between aerosol and cloud in the atmosphere. This proposal was created due to the lack of knowledge about their interactions and is reflected in their respective weather and climate models.

As a result of this comprehension gap, essential facets of the vital processes that occur during aerosol-cloud-interactions, such as cloud and aerosol microphysics, turbulent entrainment-mixing between clouds and environmental air, and turbulence-cloud-aerosol interactions are all either misrepresented or excluded altogether.

In order to address these challenges, Prof. Ladeinde, Yangang Liu from BNL’s Environmental and Climate Sciences Department, and Vanessa Lopez-Marrero from BNL’s Computational Science Initiative seek to develop a cross-cutting particle-based direct numerical simulation (DNS) model that detects minute turbulent eddies in the cloud, tracks the evolution of individual cloud and aerosol particles, and encompasses a domain comparable to large eddy simulation (LES) grid size.

The information gleaned from their research will be used to determine what aspects of weather and climate should be prioritized for study onwards.

Jason Loprete Receives President's Award for Excellence in Teaching

Jason Loprete Award 1 The 2021-2022 President's Award for Excellence in Teaching by a Graduate Student was granted to Jason Loprete, Mechanical Engineering PhD student. Jason was recognized for his outstanding work and commitment as a Teaching Assistant and as the primary instructor for MEC 301 (Thermodynamics), a large-scale, required undergraduate course.

One of the challenges Loprete faced was being able to engage students during his lessons as they transitioned from online classes to back to in-person, as the COVID restrictions eased. He prioritized maintaining their interests by making lectures as interactive as possible and by utilizing visual, audio, and kinesthetic mentor styles to encourage ease of learning. Loprete states, “The last thing I wanted to be for my students was an audiobook version of the textbook- I wanted to give them something they couldn't get at home.”

Thanks to Loprete’s efforts in optimizing his lessons, he was able to experience firsthand Jason Loprete Award 3 the impact of his teachings through the appreciation of his students, who express their thanks and inform him of the opportunities and achievements they’ve accomplished since taking his course. Loprete values these moments and believes their continued contact beyond the classroom is a measure of his success in the classroom.

His own experience with Stony Brook’s Mechanical Engineering program allowed him insight to the knowledge students had at this point in the curriculum, so he adapted his lessons according to what they may struggle to learn throughout the course. In addition, his time working as a Teaching Assistant under the guidance of faculty members such as Jon Longtin, Kedar Kirane, and Dimitris Assanis, exposed him to different teaching styles and philosophies. This encouraged him to use pieces of those methods in the classroom to develop his own technique.

Jason Loprete Award 2 Loprete extends his thanks for their support to Mandy and Dee of the Mechanical Engineering Department, as well as to Prof. Jon Longtin, whose mentorship allowed for him to take on the tasks of an instructor and student simultaneously. “I wanted to do for my students what he did for me back when I was in their shoes- and if I was able to do even half that, I would count this as a win.”

This award was presented at a ceremony held in May and hosted by the university’s Graduate School for recipients and their families. Awardees are given a certificate, a monetary award, and are expected to participate in a colloquium for Teaching Assistants prior to the start of the following Fall semester.

MEC 101: Annual Freshman Design Presentations

MEC Presentation 1 MEC 101, Freshman Design Innovation, recently concluded its first in-person semester since the COVID-19 pandemic began. Taught by Professor Anurag Purwar, the class had 150 students this year. Given its in-person format, the class was able to do its annual presentation outside of a Zoom call, allowing students to see one another’s devices and present their creations face-to-face.

Anar Nurizada, a mechanical engineering PhD student, was one of the TAs for the course. “I took this class myself in 2016, so I was kind of aware of what problems students could face throughout the course,” said Nurizada. The course teaches students STEM concepts through hands-on learning with robot design. Kits are manufactured in Prof. Purwar’s lab and given out to students to assist in their creations. MEC Presentation 2

“I was mainly responsible for manufacturing SnappyXO pieces,” Nurizada explained, “but I also helped students with their homeworks and any other issues they had during the semester. I was delighted that a lot of students were keen on understanding the material and asked good questions.”

During the pandemic, Prof. Purwar and his teaching assistants sent kits to students all over the world and had them work on their robots remotely. This year, students were able to be helped in-person with any mechanical or other difficulties they may have come across during their work.

MEC Presentation 3 Some of the teams featured include Nuts and Bolts, who created a delivery robot that uses a line and color sensor to deliver items to certain locations, The Goofy Goobers, who made a social robotic dog that responds to various stimuli, and Color Turtl.3, who created a green, turtle-appearing robot that performs motions in response to different colors and button inputs.

Nurizada was happy with the results of the course, stating, “At the end of the semester, it was interesting to see what kind of robots the students came up with and, honestly speaking, all students did a great job!”

Applied Mechanics Awards Prof. Kirane for Best Paper

The 2022 Journal of Applied Mechanics Award has been given to Professor Kedar Kirane for his published paper, entitled “Fracture and energetic strength scaling of soft, brittle and weakly nonlinear elastomers.” The award is provided by the Applied Mechanics Division of the American Society of Mechanical Engineers (ASME) to honor the best paper which has been published in the journal during the prior two years.

Along with the Journal of Applied Mechanics Award, Prof. Kirane will also receive a certificate and an honorarium for his efforts.

The Flipped Classroom: Prof. Purwar presents at ASEE Conference

Introductory engineering classes that follow the traditional lecture format have constricted aspiring students from being able to personally engage themselves in a field that demands hands-on innovation and developed expertise.

The solution Professor Anurag Purwar offers to remedy this issue is the “flipped classroom,” which he implements in MEC 101 - the Design Innovation and Robotics class offered at Stony Brook University. Here he “emphasizes learning STEM concepts in the context of robot design,” while being financially accessible due to the availability of videos on youtube.com, course material free of required textbook use, and an open robot design project site.

This course also “uses a novel, modular, and low-cost robotics kit and a state-of-the-art software for design and prototyping of robot motion,” and is based on the Mechanisms and Robotics research funded by the National Science Foundation (NSF).

Prof. Purwar has received outstanding commendations for his approach to teaching; so much so that he was invited to host another workshop during the Fall 2021 ASEE Middle Atlantic Section Conference on November 13. The workshop entitled, “Scalable and Authentic Robotics and Design Innovation Education from Freshman to Graduate Level,” taught educators a new way to structure their hands-on classes.

CEAS Excellence in Teaching Awarded to Prof. Kirane

In recognition of his abilities in and out of the classroom, Professor Kedar Kirane has been awarded the 2021 CEAS Excellence in Teaching Award. Prof. Kirane was honored for his superior teaching, as well as his innovation and ability to adapt his teaching modality under the unique and challenging circumstances of the past year and a half.

kirane teaching award 2021

“I am very glad the students like my teaching style, and I hope I can continue to improve,” said Prof. Kirane. “I thank all the students for their positive feedback about my teaching. I am also thankful to the TAs and graders assisting with the teaching, and also the entire MEC department (faculty and staff) for the support.”

After the Spring 2020 semester, when COVID had forced the semester online mid-way, many students left positive comments about Prof. Kirane’s teaching of MEC 363, a foundational course of mechanical engineering at the sophomore level. Many described him with glowing remarks; “an incredible professor,” “phenomenal,” and “a gem.” One student went as far as to say that he is, “the golden standard for what MEC classes should be, dare I say, all college classes in general.”

Prof. Kirane is currently supervising two doctoral students as well as three MS students and supervising the research of three undergraduate students. In the past, he has successfully advised eight MS graduates with thesis, and supervised ten recently graduated seniors through the MEC 499 research course, continuing his supervision throughout the pandemic to ensure that the students’ degree progress remained on track.

Outside of the classroom, Prof. Kirane is on various committees in the Mechanical Engineering Department and within the College of Engineering and Applied Sciences. He also serves on several committees within ASME and other academic societies.

“Kedar has been an outstanding junior faculty in the Mechanical Engineering department,” said Prof. Jeff Ge, the Chair of the Department of Mechanical Engineering. “He embodies the innovative spirit of the College of Engineering and Applied Sciences and I am proud to call Kedar my colleague.”

Professor Purwar Awarded $1M for Educational Robotics Framework

Purwar Award 1M Stony Brook University and Mechanismic Inc. have been awarded $1,000,000 by the National Science Foundation’s Small Business Technology Transfer (SBIR/STTR) Program for their proposal "A Design-Driven Educational Robotics Framework." The Stony Brook University team is led by Mechanical Engineering professor Anurag Purwar, who is the primary inventor of the technology and lead researcher on this project. Professor Kedar Kirane, also from Mechanical Engineering, Dr. Keith Sheppard from the Institute for STEM Education, and Erik Flynn from the School of Health Technology and Management are senior persons on the SBU team. The SBU team will be receiving a share of over $300,000 for two years, as well as an additional $80,000 from Strategic Partnership for Industrial Resurgence (SPIR).

As described by Prof. Purwar, the framework is a unified platform that is capable of teaching students engineering design, practical electronics and programming all in one place. “[It] brings a new approach to STEM and robotics education, wherein students engage in the entire design innovation cycle from conceptualization to programmable robots.”

SnappyXO Design, originally conceived by Prof. Purwar for teaching purposes, is part of the work he’s doing in this project. In the beginning, it was able to give freshman students the chance to enjoy authentic engineering design in robotics, but now it has been built upon to be something greater. “As part of this project,” he explains, “our research is going to bring together rigid body kinematics and machine learning to develop software and algorithms for an AI-driven mechanism design architecture. This software will democratize design innovation and invention and put the power of creativity in the hands of every student and engineer.”

Through a multidisciplinary approach, the platform can be a first step into a STEM discipline for any student, especially underrepresented groups such as women or minorities.

Purwar Award 1M 2 “As a child, I never got a chance to do anything related to robotics or even play with them,” said Prof. Purwar. “ I grew up in a modest neighborhood and town with little access to electronics or technological toys, which looking back, I can say confidently, would have had a major impact on me. Creating this robotics education product is my way of reliving my childhood playing, tinkering, and learning with robots and machines that I wish I had.”

The SBIR/STTR program focuses on supporting innovation by investing federal research funds with the goal of turning scientific discoveries into products and services with commercial or social benefits. Prof. Purwar’s invention was licensed by Mechanismic Inc., a NY-based C-Corporation, co-founded by him and Professor Jeff Ge which is bringing this technology to the market.

“This award will enable us to develop the next generation of hardware for robot design, software for building invention design capacity, and a standards-aligned curriculum for K-12 and college students,” Purwar explained. “[It] will lead to a design-driven educational robotics product that provides Problem- and Project-Based Learning (PBL) experiences for K-12 and post-secondary students to grasp STEM concepts in a fun, active, and engaging way.”

Professor Yao Awarded NSF EAGER Funding

Amyotrophic lateral sclerosis (ALS, also known as Lou Gehrig's diseases) is a common neuromuscular disease that has had a large share of fame whether it be from figures like Lou Gehrig or Steven Hawking, who both famously had it, or from awareness campaigns such as the ALS bucket challenge. Incurable, ALS can result in muscle weakness and atrophy that can make walking, talking and even breathing on one’s own difficult - and as they usually can still perform higher mental processes, the inability to properly communicate with others can lead to depression and anxiety. To try and address this issue, a new proposal was funded this past summer that seeks to make life for those with ALS easier.

ShanShanYao “The overarching goal of this project is to build an unobtrusive hardware-software platform for ALS patients that can capture speech-relevant lip gestures and decode lip movements for speech,” said the project’s abstract. The project, Lip Reading by Unobtrusive Multimodal Sensors and Machine Learning Algorithms, is headed by Prof. Shanshan Yao from Mechanical Engineering as a collaboration with Prof. Petar M. Djurić, Department Chair of Electrical and Computer Engineering, and Dr. Renee Fabus, Founder and Chair of the Speech Language Pathology Department at Stony Brook. The project was proposed through the National Science Foundation’s EAGER mechanism - Early-Concept Grants for Exploratory Research - and was awarded this grant in July.

ALS patients, as well as individuals with speech and hearing disorders, could all benefit from a technology that seeks to improve upon the existing methods for tracking and interpreting facial movements. This project hopes to create a skin-like multimodal strain and electromyography (EMG) sensing system capable of tracking skin deformations and muscle activities associated with lip movements and then convert these inputs into spoken word.

An opportunity for students to participate in cross-disciplinary research as well, the abstract noted that parts of the project will be integrated into coursework and capstone design projects.
This project can lay the groundwork for “developing a truly natural and unobtrusive hardware-software system,” as explained in the abstract. “Our proposed work can fill the gaps in the existing solutions by an intuitive and unobtrusive technology for lip reading.”

Memorializing the Work of Ted O'Brien

The Physics of Fluids journal released a special issue dedicated to the memory of the late Edward E. “Ted” O’Brien,” a Stony Brook University Professor Emeritus of Mechanical Engineering.

Published by the American Institute of Physics, multiple guest editors participated in this special edition including, Professor Emeritus César Dopazo of Zaragoza University, Spain, said to be one of the most celebrated students of Prof. O’Brien in academia; Professor Peyman Givi, a colleague of Prof. O’Brien and a distinguished professor at the University of Pittsburgh; and Professor Foluso Ladeinde, associate professor at Stony Brook University, founding chair of the Department of Mechanical Engineering at SUNY Korea, and a mentee of Prof. O’Brien.

Professor O’Brien was a Professor of Fluid Mechanics, a member of ASME and New York OBrien Squared Academy of Sciences as well as a Fellow of the American Physical Society. He joined Stony Brook University in 1961, when the university held its first commencement and appointed its first president. He joined the inaugural faculty as a founding professor in the College of Engineering and Applied Science and a member of the Department of Thermal Sciences. Under his leadership the program gained popularity and grew into what is now the Department of Mechanical Engineering, where he served as the Chair from 1983 to 1991.

“I am very pleased to be involved with this effort of immortalizing Ted’s name,” said Prof. Ladeinde. “It is my hope that Stony Brook University will take pride, not only in Ted’s academic accomplishments per se, but also in the international recognition of same.”

Regarded as a pioneer in the field, Prof. O’Brien made a variety of contributions to fluid mechanics and turbulent combustion specifically. From the beginning of his career in the 1950s, he made fundamental contributions to the spectral theory of reactive scalars. In the 1970s-80s, he was widely recognized for introducing and popularizing single- and multi-point probability density functions (PDF) closures within the reactive turbulent flow community. Through the 1990s to present day, his contributions continued to be well-received and highly cited to the end of his research career.

Collaborative Research Earns DOE Award to Speed Up the Transition to Electric Vehicles

Fossil-fuel vehicles are a leading cause of mass carbon emissions, resulting in the gradual temperature increase on Earth’s surface and exacerbating the acidity in rain during precipitation. In order to combat the detrimental effects this energy source has on the environment, domestic and international organizations alike have set ambitious goals to completely phase out its use in the upcoming decades. Research developments and technological innovations geared towards fully transitioning to electric vehicles and decarbonizing the transportation sector are receiving unprecedented support from the U.S. Department of Energy (DOE) and other federal agencies.

DOE Energy A collaborative research group led by a material scientist (Prof. Esther Takeuchi) includes electrochemists (Prof. Amy Marschilok, Prof. Kenneth Takeuchi) and a mechanical engineer (Prof. Carlos Colosqui). Stony Brook University has received a DOE award of more than 2.2 million dollars. The funding from this institution will be used to produce new electrolytes for high-performance lithium-ion (Li-ion) batteries that charge and discharge at accelerated speeds, even while under extreme conditions. To undertake this proposition, the researchers at SBU will consolidate efforts with scientists at Brookhaven National Laboratory and Brown University.

Titled “Fluorinated Ester Local High Concentration Electrolytes for Operation of Li-ion Batteries under Extreme Conditions,” this scientific venture is aimed towards creating a novel class of non-flammable electrolytes for Li-ion Batteries, which are essence complex fluids with a high concentration of nanoparticles that act as charge carriers in a liquid medium. Prof. Colosqui, who currently spearheads this study, strives to further understand and predict fluid flow, rheological properties, and mass and charge transport through these newly manufactured electrolytes.

“This project highlights the critical importance of interdisciplinary research and the key role that fluid mechanics will play in the transition to sustainable technologies and green energy,” Prof. Colosqui states.

SBU will be collaborating with selective research institution groups in order to advance the fundamental science and technological innovations required to decarbonize the U.S. transportation sector and combat climate change.

“[By] partnering with industry and leading research universities, DOE’s investment in these 24 projects will create technologies that will cut vehicle greenhouse emissions and boost America’s competitiveness in the global clean energy market,” the 16th Secretary of Energy Jennifer M. Granholm affirms.

Students interested in contributing to this research are encouraged to contact Prof. Colosqui at carlos.colosqui@stonybrook.edu.

Presidential Dissertation Completion Fellowship

As the majority of students return to campus, some are working to recover from COVID’s effect on their work. Vamiq Mohammed Mustahsan was the recipient of the 2021 Presidential Dissertation Completion Fellowship awarded by the SBU Graduate School. The fellowship is awarded to students who demonstrate solid achievement and steady pre-pandemic progress to their degree. It would provide two semesters of stipend support for an advanced doctoral student ($20,000) who has experienced a delay in their degree progress due to circumstances or challenges beyond their control.

Mustahsan had been on track to graduate by May of 2021 after giving his Ph.D. proposal two years prior. His research focuses on customized bone tumor resection and bone reconstruction, increasing the accuracy of bone tumor resections and developing a structurally Vamiq Mustahsan biomimetic and biocompatible implant. Ideally, Mustahsan will develop a methodology that would reduce the overall costs and vastly improve the quality of life in those who suffer from osteosarcoma - one of the most common forms of bone cancer. After the removal of malignant bone tumors, patients can be forced to deal with inaccurately fitted implants that can lead to future complications. “Most patients are forced to undergo multiple subsequent surgeries, sometimes even ultimately an amputation,” explained Mustahsan. “[However], if a very good implant fit is achieved, the lifetime of the implant is significantly improved.”

The original plan was to carry out in-vivo studies by implanting their customized implant or bone graft substitute (BGS) in mice. However, after spending the Fall of 2019 planning and preparing for the experiment, the events of early 2020 quickly forced the study to a stop.

“We started the study in the second week of February 2020 and reached the second stage of our experiment in the second week of March when the nationwide COVID lockdown was implemented,” Mustahsan said. The experiment was conducted in the department of Anesthesiology, which was shut down along with the university hospital as all available lab space was taken for COVID research purposes. The study couldn’t be returned to until October; Mustahsan and his group concluded the second stage in December 2020. Mustahsan still faced problems however, as surgery on the mice were required for the third stage by orthopedic residents and attendings familiar with bone tumor surgeries.

PDC Diagram “Even after the hospital restrictions for researchers were partially lifted in Fall, many attendings and residents were still enlisted in COVID duty. Consequently, we could not get them to do the surgeries,” said Mustahsan. The surgeries couldn’t be completed until April 2021, less than a month before Mustahsan’s planned graduation. There was no other choice but to push his graduation back an entire year in order to complete his research.

Many have seen this fellowship as well-deserved including Professor Imin Kao, Mustahsan’s Ph.D. advisor. “This fellowship reflects his work here at Stony Brook,” said Kao, describing Mustahsan’s advocacy for graduate students at Stony Brook. While managing his own experiments, he has also been working in collaboration with the Stony Brook Office of Government Affairs in the capacity of the Chair for Policy Action for State Affairs for Stony Brook Graduate Student Organization (SBGSO) and actively organizing the Science and Research Awareness Series with the Department of Anesthesiology in Stony Brook Hospital. Mustahsan also worked as a Resident Assistant for over 3 years in Chapin Apartments, a graduate student dorm that mainly houses international students and previously, was recognized with the Outstanding Leadership Award by the SBGSO.

Although COVID interrupted his original plans, Mustahsan will now complete his work and thanks to the fellowship, will complete his degree in May 2022.

NIH Funding Awarded to Professor Chen

The project “Magnetically activated structures for minimally invasive endovascular therapy" has been selected for funding by the National Institutes of Health (NIH) of over $600,000. This collaborative project features Professor Shikui Chen of the Mechanical Engineering Department, Drs. Chander Sadasivan and Apostolos Tassiopoulos from SBU’s Renaissance School of Medicine, and Professor David Gu from the Computer Science Department. Professor Sadasivan is the principal investigator and the contact of this NIH proposal.

The multi-department group hopes to tackle the dangers of abdominal aortic aneurysm (AAA). While heart disease is the leading cause of death in the US, AAA is also one of the top 15 leading causes of death in people over the age of 65, directly causing nearly 10,000 deaths per year. Professor Chen hopes to make the process of treating AAA easier with this project.

“The treatment of AAA mainly relies on minimally invasive endovascular therapy,” described Prof. Chen, “[but] the major obstacle to current endovascular treatment is that the structure of the device is not optimal relative to the patient's vascular anatomy.” The proposal seeks to use magnetically activated structures (MAS) to optimize treatment and effectively customize grafts to each patient. A non-invasive magnetic field can be used to deform MAS-grafts inside the patient so that they conform to the vascular wall and prevent leaks, migrations or anything that could lead to AAA.

“The primary goal of this project is to develop numerical schemes for multi-material topology optimization of an endovascular MAS-graft with actively controllable motion and balanced stiffness,” said Prof. Chen. “MAS designs generated from patient-specific AAA geometries will be reduced to a single design via robust design principles. Proof-of-concept of deployment and non-invasive control of the structures will be evaluated in vitro.”

Welcoming New Department Members

The Mechanical Engineering Department is happy to welcome back students and staff alike as the fall semester brings back most people to campus after roughly two and a half semesters of remote learning. The new academic year holds promise as everyone can properly take advantage of everything the Stony Brook University campus has to offer.
As well as welcoming back students returning and new, the department also welcomes back faculty returning and new. There are three new members of the department this year, Austin Giordano, Amin Fakhari, and Jie Gao.

Austin Giordano initially joined Stony Brook University as an undergraduate student in 2015. He completed his Bachelor's of Engineering in 2019, as well as a Master's of Science in Mechanical Engineering in 2021, and is pursuing a Ph.D. in our department. In the summer of 2021, Austin joined as an Instructional Support Specialist, where in this role he assists with the lab courses at both the undergraduate and graduate level. Giordano would like to assist the students with developing their passions for engineering outside of the classroom, through research, clubs or personal projects. “I'd like to welcome back all of our returning students at every level - it's good to be back on campus with all of you!” Giordano continued, “To all of the new students, I would like to welcome you to our department and to our campus. You're in for some great times over the next few years!"

Amin Fakhari joined the Mechanical Engineering faculty this Fall as an Assistant Professor of Practice, though he has been part of the Stony Brook community since 2013. Previously, he was an Assistant Professor in the Mechanical Engineering Department at SUNY Korea in 2017, and a research scholar in Stony Brook’s Department of Mechanical Engineering in 2013. He received his Ph.D. in Mechanical Engineering from Isfahan University of Technology in Iran. His research interests are in robotics, dynamical systems, control systems, machine learning, and mechatronics. He specializes in anthropomorphic robotic hands, dextrous manipulation planning, force and motion planning, object grasping analysis, soft contact modeling, and slippage control. He aims to develop robotic systems that mimic or surpass human capabilities.

Jie Gao Jie Gao joined the Department of Mechanical Engineering as Associate Professor in the Fall of 2021. She received her Ph.D. from Columbia University. Her research interests include optical and thermal energy harvesting, optical sensing and imaging, nanomanufacturing, opto-mechanics, and quantum optics. The current research projects in her lab range from novel 2D materials, optical nanostructures, infrared absorbers and emitters to light emission devices.

We’re happy to have all three of them join us and look forward to a great, safe school year.

Sean Vierling Recieves Mountain Mover Award

Sean Vierling, a senior Mechanical Engineering major, was awarded the Mountain Mover Award during this year’s Student Employee and Supervisor of the Year Awards Ceremony hosted by theUniversity Career Center. This ceremony is held every year to honor exceptional student employees and their supervisors. The Mountain Mover Award in particular recognizes those who have had a significant impact in their workplace.

“When I won the award I was very surprised,” said Vierling, “I was also extremely grateful that I have a great mentor in Professor Purwar to help me earn an award such as this.” Vierling has worked in the lab of Professor Anurag Purwar for several years and is currently a National Science Foundation Fellow there. His main focus is walking machines and robotics. He assists in the creation and development of Professor Purwar’s SnappyXO STEM kit but also designs a variety of walking-based robots. Together, Vierling and Purwar plan to write a book on this robotics work.

“I am working on a multi-degree of freedom robot for a Vertically Integrated Project class where my team and I are testing the effect of walking gaits on various terrains.” Vierling explained. “[Additionally] this semester, my Senior Design team and I are working on a prototype for a sit-to-stand device for children with Cerebral Palsy.”

When the pandemic began, Vierling’s focus shifted to encompass not only his existing projects but how to help frontline medical workers. He worked with them to create a laser cut face shield that could be pivoted away from the users face to allow them to change masks and drink without needing to take it off. He also created a laser cut N-95 face mask holder in which medical workers could keep their masks safe and separate from one another to elongate the lives of their overused masks.

Professor Purwar nominated Vierling for this award, having known him since his first year at Stony Brook. “I first met Sean in 2017 when he was a Freshman student in my MEC 101: Freshman Design Innovation class. Much impressed with his work ethic, I offered him a paid position to work in my lab. Over time, he has proved to be an exceptional organizer and leader... Without a doubt, he is the most competent and accomplished undergraduate student employee I have ever had. I wholeheartedly recommend him for this award.”

After receiving the Mountain Mover Award, Vierling was also chosen to receive the 2021 Provost’s Award for Academic Excellence. This annual award is given to a select number of graduating seniors who show academic excellence not only in the classroom, but outside of it in activities such as research and building a stronger academic community.

Next year, I hope to complete my thesis under Professor Purwar,” Vierling said. “After, I will likely look for a job in industry - preferably in the field of Robotics or Defense.

Robotic Arm-augmented Wheelchair Earns Prof. Chakraborty OVPR Seed Grant

Professor Nilanjan Chakraborty has been selected as a recipient of the Office of the Vice President for Research (OVPR) Seed Grant, for a research project entitled " Robotic Arm-augmented Wheelchair for Enabling Independent Living for People with Quadriplegia." The development of this technology required for a wheelchair-mounted robot arm could help improve the quality of life for disabled individuals.

“The vision is for people with SLD to carry out essential activities like feeding themselves, going from one room to another, using high level commands.” explained Prof. Chakraborty. “For example, the user can say ‘open the door’ and the robot arm can execute the task of opening the door, so that the user can pass through by controlling her wheelchair.” The robot arm would be interacted with through a tablet interface with hands-free inputs such as eye gaze or voice.

Other collaborators on this project are co-PI Brooke Ellison, PhD, Health Technology and Management, as well as Xiaojun Bi, PhD, Computer Science, Haibin Ling, PhD, Computer Science, and I. V. Ramakrishnan, PhD, Computer Science.

The project seeks to surmount a variety of technical challenges such as ensuring that the robot arm is capable of accurately perceiving the environment, able to understand the user's intent with commands and having the arm reliably execute the tasks in question. Prof. Chakraborty anticipates that the last of the three will be the most difficult. “Manipulation in a home environment is extremely challenging because every home is different, and consequently it is hard to pre-program the robots - as is usually done for industrial manipulation tasks.”

The research team plans to develop methods that would allow the robot arm to understand examples of tasks given to it by a caregiver and subsequently learn from these examples to independently complete tasks later on. “The caregiver will hold the hand of the robot and teach it to do a task, just as one would teach a child,” said Prof. Chakraborty. “And we want to burden the caregiver minimally.”

OVPR Seed Grant - Professor Kao

Professor Imin Kao has been selected as a recipient of the Office of the Vice President for Research (OVPR) Seed Grant, for research into removing cancers known as ‘soft tissue sarcomas’. The primary treatment for soft tissue sarcomas is removing the tumor cells entirely, but the reappearance of the cancer is a major problem in the medical industry if even a slight piece of it is left behind.

In collaboration with Assistant Professor Fazel Khan and Professor Brendan Boyce, doctors of Orthopaedics and Pathology respectively at the Renaissance School of Medicine, Prof. Kao intends to rectify this issue. “Raman spectroscopy is a non-invasive technique, which generates spectra that can reveal structural fingerprints of molecules in tissues by inelastic scattering of photons,”described Prof. Kao. “We have examined if Raman spectroscopy can correctly distinguish tumor tissue from adjacent benign skeletal muscle, dermal collagen and fat in frozen sections from resected tumors from 4 different patients and compared the results with the histologic findings in adjacent H&E-stained frozen sections.”

Through use of Raman spectroscopy, the group intends to create a reliable method of determining that the soft tissue sarcoma has been completely removed during surgery, helping the entire process occur faster and with a lowered chance of the cancer reappearing after the fact.

The funding will allow the research team to conduct experiments and acquire data from patients with soft tissue sarcomas in order to determine if their methods are capable of reliably distinguishing tissue types as well as ascertain if a portable Raman probe could be used with accuracy in the operating room. This will hopefully be a stepping stone and provide results for grant applications that have been submitted to NIH and NSF for additional funding.

Prof. Kao is decidedly optimistic on the project’s future. “Our preliminary results are very promising and show a high correlation between the histologic findings and analysis of the Raman spectroscopic data using a novel computer-generated algorithm…” he explained. “Our group has published our research findings in journals and presented them in international conferences, and will continue to do so as new results of this research collaboration emerge. We envisage that our work will have important clinical applications.”

Figure 1. Spectra of tumor, muscle, dermal collagen and fat at different locations. The spectrum of each tissue type is an average of more than 80,000 spectra among different regions and locations in the tissues, showing consistent peaks with distinct patterns for the tissue types. The horizontal axis is the wave numbers (in cm-1) and the vertical axis is the normalized intensity.

Professor Longtin Awarded $100k Subcontract

Professor Jon Longtin has been awarded a $100k subcontract for research and development on a project entitled “Oil and Gas Combustion Emissions Testing” with Brookhaven National Laboratory. The project is funded by NYSERDA, and focuses on a suite of emissions measurements for combustion heating systems according to Prof. Longtin. The project will look at both different fuel types and different combustion systems. In the wake of the Climate Leadership and Community Protection Act (CLCPA), which seeks to have New York use zero-emission electricity by 2040, information on renewable energy and emissions is in high demand. “This is a dramatic change in the landscape of how energy is used in the state, and represents New York State’s commitment to becoming the national leader in this space,” said Prof. Longtin. “I think this is very exciting to see.”

Motorsports Club Flourishes Amidst Pandemic

For one student organization, the pandemic may have been a blessing in disguise.

Stony Brook Motorsports may not be the biggest or oldest club on campus, but they have made a name for themselves in their own right. Every year the team designs, builds and races an off-road vehicle in the Baja Sae Competition - one of SAE International’s many Collegiate Design Series competitions designed to prepare future engineers for the mobility industry. In light of the pandemic, the competition has been modified from a hands-on test of skill to ‘knowledge events’ based in design, modeling and more for now two years in a row.

“Once the pandemic hit, we weren’t really able to do anything in our shop and office,” saidChristopher Sherling, the club’s

president. The competition is usually held from April-June andtheteam had just gotten to work building last year’s vehicle when Stony Brook switched to remote learning. “We focused all of our work on all-wheel drive and sorts.”

At first, the switch made it impossible to continue their work, but then the club quickly came to realize that this is just what they needed. Sherling explained that the club often had trouble bringing on new team members when it came to explaining everything that needed to be done. “We went

Motorsports

from having 15-20 pages of technical documentation on the car to over 250 pages… This ended up being one of those silver lining things where it sucks that we can’t see each other in person, but it’s had a significant benefit for the team where we can focus on design.”

The threat of a knowledge gap became a serious concern of the club, not only because the pandemic is preventing them from doing any physical vehicle work, but also because a large portion of the club’s experienced members are in their senior year and won’t be present when the club makes a shift back to in-person activities. This is only exacerbated by the fact that SAE plans to enforce a major design change requirement where all vehicles will be required to have four-wheel drive starting in 2022 rather than a standard design - something they’ve never done before.

“We’ve been able to do a lot of documentation, more so than what we’d normally be able to do,” said the club’s vice president, Nicholas De Marco. “And that’s going to help [the team] in the Motorsports futureto be able to see how people design things. We’regoing to start writing up how we fabricate things so that people in the future can know what we did and how we did it.”

Beyond vehicle work, the club does it’s best to stay together. Christian Funes, one of the club’s System Leaders described organizing game and movie nights in order to keep the club connected while being scattered across the country. “We try to keep together by doing events, like a little game night to keep the community together,” Funes explained. “It honestly really helps. Helps us come together without having to do work which, in my opinion, is a good way to build a team.”

Freshmen Design 'SnappyCat'

One class brought the remote fall semester to a close more connected than ever.

Professor Anurag Purwar teaches MEC 101, a large Freshman Design Innovation class, but was faced this year with the obstacle of holding this hands on class virtually during the pandemic. In the class, students learn STEM concepts in the context of robot design. A robot kit produced in Purwar’s lab is usually provided to each student in class. This year however, rather than being in the same room, students were scattered across the globe.

SnappyCat Group “I have seen students in my class bond over the project, make friends, and become comfortable knowing their professors and seniors who serve as mentors.” said Purwar. “I was not prepared to let go of this valuable aspect of their presence on campus.”

Despite all the limitations and constraints, Prof. Purwar and the Teaching Assistants made kits and sent them to students wherever they were in the world and had them work on their robots remotelyand virtually. This year's theme was "Design a robotic solution for someone who was affected by COVID-19".

Students bonded over this hands-on project during the last five weeks and found a way to design, build, make circuits, and program their robots, overcoming despite the hardships of their diversity in location the challenge presented by physical distance. The Mechanical Engineering Department Chair, Professor Jeff Ge, and CEAS Acting Dean Professor Rob Kukta, attended the final robot

demonstrations over Zoom, providing a morale boost for the freshman students, many of whomhave not seen the campus in-person at all. Of the 33 projects presented, one of the class’s favorites was a device named ‘SnappyCat’. This “walking” cat-shaped robot is capable of quizzing the user on basic math equations and reacting accordingly to correct or incorrect answers.

Purwar was proud of the odds the students overcame, stating, “I like to believe that it gave them a sense of community and purpose and most importantly, hopefully they made some friends and had fun in the process.”

Professor Purwar Awarded 2021 ASEE Mid-Atlantic Distinguished Teaching Award

Assistant Professor, Anurag Purwar, has been selected as the winner of 2021 ASEE Mid-Atlantic Distinguished Teaching Award. The American Society for Engineering Education (ASEE) Mid-Atlantic Section is committed to excellence in engineering and engineering technology students' instruction and annually recognizes an outstanding engineering or engineering technology educator from the section. This award is in recognition of Prof. Purwar's outstanding contributions to teaching and learning at Stony Brook University.

The award consists of an honorarium and a certificate of recognition, which will be presented at the Awards Ceremony of the 2021 virtual spring meeting, hosted by Villanova University on April 9-10. Prof. Purwar will share his expertise and experience as an educator with the ASEE community at the conference.

Additionally, Prof. Purwar has been nominated as the Mid-Atlantic Section’s representative for the ASEE National Outstanding Teaching Medal for 2021.

While the award recognizes his dedication to his students and his continued development as an exceptional instructor, Prof. Purwar humbly believes that this award is also a nod to the Mechanical Engineering department, the College of Engineering and Applied Sciences, and Stony Brook University as a whole.

Manufacturing Day 2020

To celebrate the national Manufacturing Day on October 2, members of the College of Engineering and Applied Sciences joined Long Island’s manufacturers, SBU alumni and advocacy groups to spread some much-needed knowledge about the industry. Local high school students and parents Manufacturing Day attended ‘Long Island Manufacturing Day 2020’ held by Summit Safety & Efficiency Solution and explored career possibilities in the industry. They learned from recent graduates about the early years in a manufacturing career, experienced virtual tours of manufacturing factories, and enjoyed a virtual robotics camp at the end of the event.

Joseph Schurz, Machinist for the CEAS and Mechanical Engineering (MEC) instructor for Machining Practices, is one of many who appeared in panels and Q&As to impart advice on those who attended. “Although it can be hectic at times, seeing the students grow into the engineers they came here to be is what makes me proud to be a part of the MEC department,” Schurz said. When presented with the opportunity to participate in Manufacturing Day and speak to younger students on the possibilities within the field, he “couldn’t turn it down”.

Professor Noah Machtay also attended this event for similar reasons, stating that, “Outreach efforts to primary and secondary school students has been a consistent part of my work throughout my career. I'd hate to think some promising young engineer might miss their calling to our field just because no one ever showed up to tell them about it.” Machtay instructs the Manufacturing Processes course at Stony Brook as well as supervises the MEC department's Manufacturing Automation Laboratory.

The manufacturing field has a variety of possible careers within it usually related to creating new products from raw materials or simple components - factories are usually what comes to mind for most people but it’s so much more than that. “Engineers solve problems,” Machtay explained. “And for mechanical engineers, that often means designing a physical structure or device of some kind. I like that by incorporating the manufacturing field, we can ensure that the things we design are genuine solutions that work both on paper, while also being feasible in the real world.”

The typical jobs that MEC students get when they take the manufacturing track range from machinists and manufacturing engineers to working in aerospace and robotics. Some of the brightest outlooks can be found for industrial engineers and sales representatives in the industry.

Industrial engineers design, develop, test and evaluate integrated systems for managing industrial production processes - such as managing a facility or plant, ensuring quality in products or working with research and development. Sales representatives on the other hand, work to sell the created products on behalf of the manufacturers to businesses. Having an engineering background and substantial knowledge about the items that are being sold are key skills that can set you apart from the competition.

Schurz described manufacturing as having good and bad attributes, stating “Being able to design and manufacture something by hand is a challenge that I love to take on. The thing to dislike is occasionally on the job you have to deal with poorly conceived designs and improperly drawn blueprints.”

When it comes to people entering the field, he posed a simple piece of advice. “Understand the field you are about to dive into…It's not all about sticking your nose in the books and studying for 50 hours a week but it's also important to be hands on in order to become a well-rounded asset to your job/community and embrace the challenges that lie ahead.”

SUNY Technology Accelerator Fund S4 Catalyst Investments

One class just made it big with a little platform known as SnappyXO (www.snappyxo.com). Stony Brook’s team placed first in the inaugural 2020 SUNY Technology Accelerator Fund S4 Catalyst Investments competition from the SUNY Research Foundation. The SUNY-wide competition is the capstone of the SUNY S4 Startup school and grants two winning teams $10k each.

This year’s victor, SnappyXO, is a state of the art STEM and Robotics education platform to encourage students from K-12 and higher-education to learn STEM concepts using project-based and experiential learning.

The product was invented in Professor Anurag Purwar’s Computer-Aided Design and Innovation Lab in the Mechanical Engineering department and builds upon years of research in the Mechanisms and Robotics area. It comes with a patented hardware and an app for motion design of mechanisms and robots. The technology behind the product has been licensed to a NY-state startup Mechanismic Inc., which is bringing this to the world-wide market now.

Ameya Kale, a recent Stony Brook graduate with an MS in Mechanical Engineering, is now leading the product and business development efforts at Mechanismic Inc. “There were a total of 14 teams that participated in the competition, and each of us had really good and innovative ideas.” Kale pitched the product at the competition, helping SnappyXO impress the judges.

“Personally, I had never pitched before in my life and so I was going in with big expectations of myself. It was a great learning experience for me, and I am happy that my efforts led to positive results in terms of the competition!”

Stony Brook University and Mechanismic Inc. have been jointly developing the technology and the product with the funding from the National Science Foundation, Manufacturing Technology and Research Consortium (MTRC), SUNY Research Foundation, SensorCAT, and the NY-state SPIR program.

US Navy Awards Professor Kedar Kirane

ONR logo The Office of Naval Research (ONR) may provide technical advice to the Navy, but where would they get this research information but from one of our very own? Professor Kedar Kirane of the Department of Mechanical Engineering has become one of the lucky researchers to receive a grant from the ONR this summer, enabling him to bring his research to new heights.

Professor Kirane received an award of $490,000 that will be given over the course of a three year long project to investigate the size effects in fabric composites failing under compression. Woven fiber reinforced composites under compression predominantly fail by the formation and propagation of a fiber kink band. While the underlying physical micro-mechanisms have been widely analyzed, the ensuing scaling in the strength has not. This is essential to understand, in order to assess the load bearing capacity of composite structures of different sizes under compression, by using strength measured on lab-scale coupons. This project will pursue this understanding via a combined experimental and computational approach.

Just recently, Professor Kirane was announced for winning ASME’s ORR Early Career Award for his research on understanding the fatigue, fracturing and scaling behavior of various conventional and advanced composite materials. And last year, he won the Army’s Young Investigator Program with his proposal to quantify how much energy composites can safely absorb. His extensive research in these specific facets certainly caught the eye of the ONR.

ORR Early Career Award Recieved by Professor Kedar Kirane

Professor Kedar Kirane has been awarded the ORR Early Career Award by the American Society of Mechanical Engineers (ASME). The award recognizes Professor Kirane for notable research excellence for his work with solid mechanics, focusing on the fracture, fatigue and scaling in heterogeneous quasi-brittle materials such as composites and concrete.
Many Stony Brook professors have made names for themselves within ASME, including Professor Toshio Nakamura, the current chair of the ASME Materials Division, and Professor Jeffery Ge who is the current past chair of ASME Design Engineering Division. Students are no exception with the ASME Student Chapter at Stony Brook participating in many projects of their own, including the ‘Go Baby Go’ Program that provides hundreds of mobility disabled children specialty cars that cater to their needs.

Professor Kedar Kirane Established in 2004, the ASME ORR Early Career Award is given by the Orr family through the Materials Division of ASME and consists of a $3,000 honorarium and certificate. It is given annually at the International Mechanical Engineering Congress & Exposition, and will be presented virtually to Professor Kirane in November.

Introducing STEM Concepts at a Freshman Level via a New Design-Driven Robotics Class

The American Society for Engineering Education hosted their annual conference virtually this year, giving Professor Anurag Purwar the opportunity to host a workshop for fellow educators. Prof. Purwar's objective: "For too long, a large majority of Engineering departments have sought to introduce Engineering concepts to Freshman students by creating watered-down, lecture-driven “Introduction to Engineering or XYZ” classes. However, in recent years, Engineering educators have mandated an introduction of design concepts, innovation, entrepreneurship, and projects early in a student's education, promote teamwork, and introduce modern engineering tools. The National Academy of Engineer's “The Engineer of 2020" report concludes that the passive, lecture-based instruction should be replaced or supplemented by active, integrated, project-based learning with significant design components. It is not uncommon to see various academic institutions introducing design and innovations early in the curriculum and emphasize preparing and educating engineers who can excel in a creativity- and innovation-based economy.

The goal of this workshop is to introduce Engineering educators to a new hands-on, project-based, and flipped Freshman Design Innovation and Robotics class offered at Stony Brook University and created with a Teaching Innovation grant from the State University of New York (SUNY). The class emphasizes learning STEM concepts in the context of robot design and is enabled by a set of videos freely available on youtube.com, text-book free course material, and open robot design project site. The class also uses a novel, modular, and low-cost robotics kit and a state-of-the-art software for design and prototyping of robot motions. The software is built upon the NSF-funded research in Mechanisms and Robotics. The software and the robot kit are also being used in undergraduate and graduate Kinematics classes at Stony Brook University."

Professor awarded NCI funding for research in engineering-driven medicine

Professor Jeff Ge has been awarded a two-year grant in the amount of $173,375 from the National Cancer Institute (NCI) for his project entitled, "A Dual Quaternion Based Method for Estimating PTV Margins in Intensity-Modulated Radiotherapy." The specific aim of this project is to construct a space around an imaged anatomic target, termed Planning Target Volume (PTV), that will encompass its expected positions as the body moves during image guided therapy. Current methods do not accurately capture displacements produced by rotations of the body. Consequently, treatment is directed at target volumes that are exaggerated or inadequate, jeopardizing the tolerance and efficacy of treatment. Margin differences as small as 2mm have been found to substantially increase doses to critical structures in radiation therapy. The objective of this project is to develop a method for computing planning target volume that minimally encloses the space to be occupied by the target as a convex hull of boundary positions using dual quaternions to represent the anatomic translations and rotations. The long term goal of this research is to reduce the morbidity of treatment and provide greater assurance of target coverage by a more rigorous formulation of target margins. This research will be carried out in collaboration with Mark Langer, MD, Clinical Professor, Radiation Oncology Department, Indiana University Medical School.

Engineering-Driven Medicine: CoreVent 2020

As the coming storm of the COVID-19 pandemic loomed in the New York metropolitan region in early March, the faculty and staff of Stony Brook University Hospital (SBUH) started mobilizing to address the grim predictions of shortages of critical equipment needed to empower clinicians to save lives. In response to the crisis, the CoreVent 2020 was developed by a team of mechanical engineering faculty, respiratory care clinicians, and physicians, in an extraordinary example of engineering-driven medicine. Using only readily available components, the team took on the daunting task of conceiving, designing, building and testing a ventilator that could be made available to SBUH and other clinicians when and if a critical shortage arose, thereby saving lives when the number of patients needing mechanical ventilation exceeded ventilator reserves.The team was led by Jon Longtin, professor of mechanical engineering and CEAS Associate Dean of Research and Entrepreneurship, and included Dimitris Assanis, assistant professor of mechanical engineering. Discussions are underway with Long Island-based company Biodex Medical Systems to manufacture the initial CoreVent 2020 units as the COVID-19 crisis dictates. The team has also engaged the appropriate regulatory agencies to explore pathways that will allow emergency use of the device at Stony Brook Hospital and other institutions as well. Read more

A Tribute to the Late Emeritus Professor Edward E. O'Brien

If there was a conference that Edward E. O'Brien attended consistently during his lifetime, it was the Division of Fluid Dynamics (DFD) of the American Physical Society (APS), of which he was a Fellow. At the November 2019 APS/DFD meeting in Seattle, WA, three colleagues of the Emeritus Professor, affectionately known as Ted, organized two sessions to honor his seminal contributions to the theory of turbulence. ted

Cesar Dopzao (Spain), Peyman Givi (University of Pittsburgh), and Foluso Ladeinde (Stony Brook University) compiled and shared 18 presentations at two sessions honoring Ted. Presenters came from all over the world: China, Peru, Spain, England, and of course the US. By far the most emphasized credential of Ted, besides superior intelligence, was humility. It has been said that Ted may have contributed more to Turbulence Theory than any other person in the world since the 1960s. Yet, unlike most of his colleagues, Ted was unusually modest about his acheivements.

Ted was a founding member of the Department of Thermal Sciences at Stony Brook University in 1961. The program quickly gained popularity and developed into the Department of Mechanics, later becomming the Department of Mechanical Egineering, of which Ted served as Chair.

The compilation has been made available to the public as a celebration of the legacy that Ted left behind on Theoretical Mechanics and the particular subject of turbulence theory.

Prof. Anurag Purwar (PI) and Jeff Ge (Co-PI) win a three-year $440,735 prestigious NSF award for conducting their research on A Computational Framework for Data-Driven Mechanism Design Innovation

Recent trends in democratization of manufacturing capability such do-it-yourself hobby shops, 3D printing technology, as well as low-cost sensors, actuators, and microcontrollers, call for a corresponding democratization of design tools that can help engineers and tinkerers alike to innovate and invent motion generating devices. Motion generation is a fundamental aspect of machines, at the heart of which are kinematic mechanisms that make it possible for motions to be transmitted or transformed. A kinematic mechanism is a collection of moving pieces linked together through kinematic joints such as hinge joints and sliders. Mechanism design innovation involves the selection of an appropriate mechanism type (i.e., the number of moving pieces and joints as well as the pattern of their interconnections) and the determination of key dimensions in the mechanism needed to generate the desired motions. Once a mechanism type is selected, the appropriate dimensions can often be determined by solving a system of polynomial equations. The task of type selection, however, is not so amenable to mathematical treatment, and requires a level of intuition that may take many years to develop and is difficult to pass on. This award supports the development of a set of web-based, data-driven design tools that unify the type and dimensional synthesis for mechanism design innovation. The planned MOOC (massive open online course) will help bring these tools to the masses and help promote interest in science and engineering including high school students and those from under-represented groups. The research team will bring together the diverse fields of reverse engineering, computational shape analysis, and design kinematics to develop a data-driven paradigm for kinematic synthesis of mechanical motion generation devices. The goal is to advance the science of mechanism design and lead to practical and efficient design tools capable of solving highly complex motion generation problems faced by machine designers. Central to this research is the creation of a new computational framework for simultaneous type and dimensional synthesis of various mechanisms.

Stony Brook professor develops lift for seniors

Published: March 28, 2013 6:44 PM
By JOE RYAN joe.ryan@newsday.com

Photo credit: Daniel Brennan | Stony Brook University professor Anurag Purwar with his Mobility Assistant device, used by Michael Geronimo, 90. (March 27, 2013)

The idea for the product came to Anurag Purwar when his friend, a retired physician, complained of struggling to do what so many younger people take for granted: sitting and standing.

So Purwar, a Stony Brook University mechanical engineering associate professor, designed a device resembling a walker that's equipped with an electric motor to lift seniors from chairs, then ease them back down. Now he is working with Biodex Medical Systems Inc. of Shirley to develop it into a full-blown product.

"There are so many people who need help standing and sitting as they grow older," Purwar said.

The collaboration between the professor and Biodex is part of a growing push on Long Island to commercialize technology from Stony Brook and other research facilities. Officials hope the brainpower of local laboratories will spawn a culture of high-tech start-ups to boost the region's struggling economy.

Purwar and Biodex have $80,000 to develop the invention, primarily from The Research Foundation for SUNY. They plan to target nursing homes, hoping to sell about 500 of the products annually for around $5,000 apiece. They plan to pitch the device as a way to help nurses and other employees avoid back injuries while helping patients out of chairs.

The challenge, industry experts say, will be making the device lighter, cheaper and more versatile than existing products.

"Back injuries are a huge issue, and there are already products out there," said Robert Heppenheimer, chief executive of the Nesconset Center for Nursing & Rehabilitation, who isn't associated with the product. "But if this one is cheaper and easier for nursing homes to use, there could be a market."

The bigger potential, however, could be selling the product for seniors to use in their homes, Heppenheimer said.

Purwar designed the device, called the Mobility Assistant, with help from a student, Thomas Galeotafiore. It's powered by a 12-volt battery, weighs about 30 pounds and is equipped with wheels to function also as a regular walker -- a feature Purwar says sets it apart from other products.

Ed Behan, a Biodex vice president, met Purwar last year at a workshop at Stony Brook for aspiring entrepreneurs. The company, founded in the 1950s as Atomic Products Corp. to develop equipment for researchers at Brookhaven National Laboratory, manufactures a variety of medical devices. Behan hopes to have Purwar's invention on the market within 18 months.

"More and more people want to maintain their independence and mobility," he said. "And this fits that need perfectly."

Stony Brook Team Wins National Award For Technology that Harvests Energy from Railroad Train Vibrations

STONY BROOK, NY, November 15, 2012 – Stony Brook University engineers have won a national award for an innovative energy harvester that has the potential to save millions of dollars in energy costs for railroads while
reducing carbon dioxide emissions. The team’s work, “Mechanical Motion Rectifier (MMR) based Railroad Energy Harvester,” was awarded “Best Application of Energy Harvesting” at the Energy Harvesting and Storage USA 2012 conference, held in Washington, DC on November 7-8, 2012.The Stony Brook team, led by Professor Lei Zuo and two graduate students Teng Lin and John Wang from the Department of Mechanical Engineering and Advanced Energy Research and Technology Center, developed a new type of energy harvester that converts the irregular, oscillatory motion of train-induced rail track vibrations into regular, unidirectional motion, in the same way that an electric voltage rectifier converts AC voltage into DC. Professor Zuo estimates that the invention could save more than $10 million in trackside power supply costs for railroads in New York State alone, along with a reduction of 3000 tons per year of CO2 and a half million dollars of electricity savings.
