Ki-Hun Jeong is currently a full professor and the department head in the Department of Bio and Brain Engineering at KAIST in Korea, as well as an co-director at KAIST Institute for Health Science and Technology since 2006. He received a PhD from the University of California at Berkeley in 2005. His previous research interest during PhD and postdoctoral studies at UC Berkeley was the design, microfabrication, and measurement of biophotonic MEMS for biomedical applications such as biomimetic advanced photonic devices, nanomechanical biophysical sensors, nanogap based dielectric spectroscopic biosensors, and MEMS endoscopes. In particular, his main achievement on biomimetic advanced photonic systems was published in Science in 2006, entitled as “Biologically Inspired Artificial Compound Eyes”. This work received huge attentions from over 40 international/Korean News media. This work provides a new paradigm for developing wide field-of-view imaging or motion detection in surveillance detectors, mini-robots, and miniaturized imaging systems such as endoscopes, digital cameras or mobile phones. His current research interests at KAIST include nanophotonics and Optical MEMS that can be inspired from biology and also utilized for advanced biological science or biomedical applications. After he joined at KAIST as an assistant professor in 2006, his academic backgrounds have been more focused on functional MEMS camera for endoscopic applications and nanoplasmonic sensors for healthcare applications.
