received the BS, MS, and PhD degrees in electrical engineering from Seoul National University, Seoul, Korea, in 1986, 1988, and 1992, respectively. His graduate research concentrated on design, fabrication, and characterization of silicon magnetotransistor. From 1992 to 1993, he was a JSPS Fellow with Tohoku University, Sendai, Japan, where he was involved in research on linear silicon microactuators using microelectromechanical system technology.
In 1994, he joined the faculty of the department of electrical engineering, Dankook University, Gyeonggi-do, Korea, where he is currently a professor with the department of electronics and electrical engineering. From 2003 to 2004, he was a visiting professor with the Center for Intelligent Materials and Systems, University of Washington, Seattle, where he was involved in research on surface plasmon resonance (SPR) biosensors. In 2016, he was an guest professor with Institute for Biomedical Engineering, ETH Zurich and an visiting researcher with Center for BioMicrosystems, KIST.
He has conducted extensive research on medical applications of shape memory alloy actuators and electroactive polymers, biosensors using SPR, and microbial fuel cells using single cells.
