He received the B.S. degree from Seoul National University and M.S. from Iowa State University along with the Graduate Research Excellence Award. Upon joining the faculty at UCLA in 1993, he has developed several MEMS courses and established a MEMS Ph.D. major field in Mechanical and Aerospace Engineering Department. Directing the Micro and Nano Manufacturing Laboratory, he is also an IRG Leader for the NASA-funded Institute for Cell Mimetic Space Exploration (CMISE) and a member of the California NanoSystems Institute (CNSI) at UCLA. His research is in MEMS and Nanotechnology, including design and fabrication of micro/nano structures, actuators and systems, with a focus on the use of surface tension. Prof. Kim is the recipient of the 1995 TRW Outstanding Young Teacher Award, the 1997 NSF CAREER Award, and 2002 ALA Achievement Award.

Prof. Kim served as Chairman of the Micromechanical Systems Panel of the ASME (American Society of Mechanical Engineers) DSC Division and co-organized the MEMS Symposia between 1994 and 1996 for the ASME International Mechanical Engineering Congress & Exposition. He also organized the 1996 ASME Satellite Broadcast Program on MEMS and the 6th IEEE International Conference on Emerging Technologies and Factory Automation. Prof. Kim has served on numerous Technical Program Committees, including the IEEE MEMS Conference, Transducers, and the SPIE Symposium on Micromachining and Microfabrication and in the U.S. Army Science Board as Consultant. He is currently serving as a Subject Editor for the IEEE/ASME Journal of MEMS and chairing the Devices and Systems Committee of the ASME Nanotechnology Institute. With his spare time, he is also active in the commercial sector, as a board member, scientific advisor, consultant, and co-founder of start-up companies.
