Ki-Hun Jeong is currently an associate professor in the Department of Bio and Brain Engineering at KAIST in Korea, as well as an co-director at KAIST Institute for Optical Science and Technology since 2006. He received a PhD from the University of California at Berkeley in 2005. His previous research interests during PhD and postdoctoral studies at UC Berkeley were 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. 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, 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
6. 내용 :
Insects provide diverse ultrastructures for vision such as imaging, illumination, or camouflages to overcome the scaling limit in optics. For example, natural compound eyes realize wide field-of-view with a single lens platform by hemi-spherically arranging ten thousands of ommatidia in a single eyelet. Recently micro and nanofabrication enable the emulation of three dimensional structures as well as the optical functions. We reports some engineering efforts and applications for mining the smartness from insect vision organs by using multi-dimensional micro-and nanofabrications.
