Who I Am
I'm an electrical engineering student at the University of Cincinnati and a member of Bearcats Electric Racing, where I work on the car's electronics: circuit boards, firmware, and the test setups used to check them.
On the team I've designed a data acquisition board for next season's car and, with a teammate, built a bench for testing battery cells. Outside the team I build my own projects, including a star tracking mount, a reflow oven and an electric go-kart.
I'm looking for a spring co-op in embedded, electronics, or test engineering.
