I am a professor in the Department of Electrical Engineering at KAIST. I am also serving as a KAIST Chair Professor and hold an affiliated faculty position at the Graduate School of Information Security at KAISTI received PhD degree from the computer science department at the University of Southern California under the guidance of Gene Tsudik. I received my MS and BS degrees in Mathematics from Yonsei University in 1993 and 1991. Between 2002 and 2012, I was an associate/assistant professor in the Department of Computer Science and Engineering at the University of Minnesota - Twin Cities.  Before joining U of Minnesota, I worked as a research staff for two years in Sconce Group in UC Irvine. Before coming to the US, I worked 6 years in ETRI for securing Korean cyberinfrastructure. I received NSF career award on storage security and McKnight Land-Grant Professorship Award from University of Minnesota in 2005. Currently, I am serving as a steering committee member of NDSS (Network and Distributed System Security Symposium). My current research interests include security issues for various systems such as social networks, cellular networks, P2P systems, medical devices, storage systems, mobile/ad hoc/sensor/cellular networks, and anonymous communication systems.

Advertisement: I am looking for graduate and undergraduate students, who are interested in working on security issues for various systems. I am *NOT* looking for international students at this point.

Research Interests and Publication by Area

I am interested in security of emerging and current systems. My research (almost always) involves design/implementation of attacks, design/implementation/analysis of secure systems. Over the past 10 years as a faculty member, I've been working on security of various systems, which are going to expand more in the future. List below was impossible without many bright and hardworking students.
