Andrew Nwuba began doing research in his sophomore year, and joined two different research groups in the Department of Mechanical Engineering: one specializing in fluid mechanics, one focused on solid mechanics. In Professor Carlos Colosqui's research group, Andrew currently investigates the behavior of fluids, quantifies data-powder wettability, contact angles and surface tension in MATLAB, and seeks to develop new technologies related to hydrophobic materials. In the research group of Professor Fu-Pen Chiang (where Andrew worked for ~ 3 semesters until April 2018), Andrew used laser speckle interferometry to measure the strain and roughness of objects. This research involved using MATLAB scripts to generate random speckle patterns. An in-depth interview with Andrew can be found here.

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 firstname.lastname@example.org
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 VibrationsSTONY 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.
