Kofi's primary interest is in analog integrated circuits for nonlinear signal processing. This work has applications in low-power electronics for implantable and wearable biomedical devices, as well as in autonomous sensor systems. Kofi received the Cornell International Scholars and Students Award to study at Cornell University, graduating magna cum laude with a B.Sc. in electrical engineering and a minor in computer science in 2002. He studied as a Cornell African Development Fellow to receive the M.Sc. in electrical engineering, under Bradley Minch in 2004. He then worked in Paul Hasler's lab at the Georgia Institute of Technology, earning the Ph.D. in electrical engineering in 2008.​
