Prof. Ki-Hun Jeong’s Research Statement at KAIST

Ki-Hun Jeong is currently an associate professor in the department of Bio and Brain Engineering at KAIST in Korea, as well as an associated director at KAIST Institute for Optical Science and Technology. He received a Ph.D. in mechanical engineering from the University of California at Berkeley in 2005 after a B.S. and M.S. degree in mechanical engineering from Sungkyunkwan University in 1996 and 1998. After a post-doctoral position in the department of electrical engineering at UC Berkeley in 2005-2006, he joined at KAIST as an assistant professor in the department of bio and brain engineering in 2006.

His previous research interests during PhD (Adviser: Prof. Luke P. Lee in BioE) and post-doctoral (Adviser: Prof. Ming C. Wu) studies at UC Berkeley were the design, microfabrication, and measurement of biophotonic MEMS for biomedical applications such as biomimetic advanced photonic devices [1-7], nanomechanical biophysical sensors [8-10], nanogap based dielectric spectroscopic biosensors [11-16], 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 imagingor 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 Optical MEMS and nanophotonics 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, his academic backgrounds on photonic design, diverse micro/nanofabrication, and photonic measurements have been modified and stimulated to focus on the following three specific topics among broad biophotonic areas, also aligned with the personal academic strength as well as the long term objectives of the department of bio and brain engineering at KAIST. For last four years of 2007-2010, he achieved 4 SCI journal papers, 1 domestic review paper, 42 domestic and international conference proceedings, 43 domestic and international invited talks, 11 Korea and PCT patent filings, and 1 technology licensing.

His major focused areas of research are as follows,
A. Biologically inspired photonics at small scale
B. Nanobioplasmonics
C. Microendoscopy
