Dr. Chang-Gun Lee received his BS, MS, and Ph.D. degrees from the Department of Computer Engineering at Seoul National University in 1991, 1993, and 1998, respectively. During his study as a Ph.D. candidate, he was a member of the Real-Time research group at Seoul National University. He was also a visiting student to the University of Virginia from Jan. to Mar. 1996 to work with Prof. Son in the Computer Science Department. From March 1998 to Feburary 2000, we worked for LG Information & Communications Ltd. developing real-time software platform and UMTS signaling protocols for IMT-2000 mobile terminals. From March 2000 to July 2002, he was a Post Doctoral Research Associate in the Department of Computer Science at University of Illinois working with Prof. Sha. He joined the Department of Electrical and Computer Engineering, Ohio State University from August 2002. His research interests include:
