As a member of the Ohio State EcoCAR team, Chance Carafice was familiar with CAR before he began his internship. “Being on the EcoCAR team, I learned about the variety of cool stuff that takes place at CAR,” said Carafice. “The people that work at CAR are great engineers and insanely intelligent. Having the opportunity to work with them is always a huge bonus to my learning experience at OSU!”

Carafice is pursuing a bachelor’s degree in engineering physics with a specialization in aerospace engineering. He hopes to one-day conduct research related to vehicle automation, drones or aerospace.

This summer, he is working with Prashanth Ramesh in the Battery Lab, setting up a sensor suite using Arduino boards to send notifications via the cloud, of a power outage. “When power outages occur in Columbus, CAR’s power also goes out,” said Carafice. “The battery lab has tests that need to run continuously for days, if not months, so Prashanth needs to know when a power outage occurs. This is because the cooling chambers go down but the batteries keep running because they are their own power source and, with the chambers down, the batteries can melt inside the machine. The end goal is to have sensors to alert Prashanth of power outages that he can view online and be notified so that when it happens, it can be taken care of immediately.” 

Carafice said he has most enjoyed working on technical problems especially with people in a variety of fields because everyone has a different viewpoint. He has also enjoyed working with Prashanth because he has learned a lot from him about how batteries work.

In addition to his involvement with EcoCAR, Carafice is also part of the Glacier Environmental Change Group at the Byrd Polar and Climate Research Center.

Rebecca Webb has already gained some real world experience in the automotive engineering. She previously worked at Toyota as an Evaluation Engineer before pursuing her master’s degree in mechanical engineering at Ohio State. “Coming into graduate school, my goal was to deepen my level of expertise in automotive engineering while working in a collaborative environment,” said Webb. “CAR is the best place for me to accomplish these goals.”  

Webb’s work at CAR is primarily focused around electrification and modelling/simulation under the direction of Professor Marcello Canova. “There are a lot of efforts towards identifying next generation materials that can improve the energy density of lithium-ion cells,” said Webb. “My research focuses on modelling, simulation and performance prediction of next generation lithium-ion variants.”

In addition to her love of engineering, Webb also loves animals. She has a pet cat named Red.


CAR is hosting two interns from the RISE Summer Program. An internship program sponsored by the National Science Foundation that focuses on sustainable energy opportunities for incoming PhD students.

“I was interested in the RISE Program because of its focus on sustainable energy,” said David Mapunda who will begin his PhD in aerospace engineering under the direction of Professor Giorgio Rizzoni in the spring. “I think it is something everyone should be interested in because it’s providing a sustainable future for humanity.”

Mapunda is currently working on the NASA ULI project with Rizzoni and Research Scientist Matilde D’Arpino. This is his first time as a student at Ohio State and he is experiencing it entirely virtually, from China.

“Working completely virtually certainly has its ups and downs,” said Mapunda. “On the downside, I spend most of my time staring at my computer screen reading papers, planning my presentations etc. I’m an outdoor person so this feels like a huge task. However, the upside is that despite being miles away, I still get to work and learn from expert faculty in the field of electric vehicles, which are the core for future mobility. Throughout the process I am maturing as a scholar and a future engineer.” 

Mapunda has most enjoyed his interactions with Rizzoni and D’Arpino during his internship. “It’s the best because not only are they experts in their field, but they also make me feel welcome,” said Mapunda. “I feel like I’m part of the team and that makes me feel at peace so that I can focus all my energy on the project that I’m working on.”

By interning at CAR, Mapunda has been able to meet others in the RISE program and talk to them about their experiences. “It’s been interesting to get to meet people and hear their stories coming from different areas and experiences and what they are interested in and how they want to use their knowledge in sustainable engineering,” he said.

“I always wanted to learn more about technologies and operations of electric vehicle charging stations, and Dr. D’Arpino’s project with second-life batteries was the perfect research opportunity for me,” said Myung Bae Koh, who is pursuing his bachelor’s degree in electrical engineering.

Koh is utilizing Dynamic Programming to maximize the revenue when second-life batteries are applied to ancillary services. “This finding will assist in planning the optimized DC-fast charging (DCFC) station operations with grid services and simulating the station models,” he said. 

Koh says that his experience at CAR has been very enjoyable because of the professional, intelligent and kind people he works with. “I am able to openly discuss the theories or applications of the research with students and staff,” said Koh. “I like being in a team that tries to accomplish meaningful goals in the project. 

On the weekends, you’ll likely find Koh on the tennis courts, as he recently began playing tennis.

Gurpreet Singh is spending his summer at CAR working on a project that uses second life batteries to provide a faster DC charging solution for electric vehicles without always using the higher power from the grid. “This helps to reduce the energy costs by peak shaving and charging the batteries at cheaper rates,” said Singh who is pursuing his master’s degree in electrical and computer engineering.

“I was involved in some automotive projects during undergrad and gained so much knowledge from those experiences,” said Singh. ”I like working on vehicles and their technology. CAR was a big reason for me to join Ohio State and follow the path of working on EVs and new energy vehicles.”

Singh credits CAR Research Scientist, Matilde D’Arpino for his positive experience at CAR. “I think my mentor, Dr. Matilde D’Arpino is one of the most knowledgeable and skilled persons I know,” said Singh. “Working with her and the other team members on the project is amazing. It always excites me to expand my knowledge area and learn new things.”

“CAR is revolutionizing transport but not just for cars,” said Rowan Flynn, an undergraduate student in the Department of Aerospace Engineering. “It’s nice to see the versatility that comes with the work that goes on here. I want to work towards a future of carbon neutrality in our transportation, so electrification in air transport is exactly up my alley.”

Flynn is working with Professor Marcello Canova, Research Scientist Matilde D’Arpino and Lead Engineer Prashanth Ramesh on a project sponsored by NASA that focuses on the development of next-generation hybrid electric aircraft. Their work is centered around determining types and sizes of batteries to use in the propulsion system and how to best use the energy stored in that battery to improve fuel economy and reduce fossil fuel emissions.

“I have really enjoyed the supportive staff,” said Flynn. “With this sort of project there is a lot that I just don’t know, but through literature they have given me, they have all been really helpful in catching me up with the project and being accommodating, just knowing there is a lot of stuff for me to learn.”

Outside of CAR, you’ll find Flynn tending to the nearly 20 plants in their apartment. They have even begun to propagate a few!
