Biography
Duhee Kim is currently pursuing an integrated M.S.–Ph.D. program (since March 2020) in the Department of Electrical Engineering and Computer Science (EECS) at the Daegu Gyeongbuk Institute of Science and Technology (DGIST), South Korea. He received his B.S. degree in Engineering from the School of Undergraduate Studies at DGIST in February 2020.
His research interests include the development of flexible and transparent ultrathin metal electrodes for neural recording and stimulation, multifunctional biochips, wearable bio-interfaces, printed electronics, and organic electrochemical transistors (OECTs). His work focuses on creating advanced bio-interfacing platforms that integrate electronics with biological systems for next-generation biomedical applications.
