Prof. Li Qiu received the B.Eng degree from Hunan University, Changsha, Hunan, China, in 1981. He received the M.A.Sc. and Ph.D. degrees from the University of Toronto, Toronto, Ont., Canada, in 1987 and 1990, respectively. He joined Hong Kong University of Science and Technology, Hong Kong SAR, China, in 1993, where he is now a professor of Electronic and Computer Engineering. Prof. Qiu's research interests include system, control, information theory, and mathematics for information technology. He served as an associate editor of the IEEE Transactions on Automatic Control and an associate editor of Automatica. He is now a Distinguished Lecturer of IEEE Control Systems Society and the general chair of the 7th Asian Control Conference, which is to be held in Hong Kong in 2009. He is a fellow of IEEE. Prof. Kemin Zhou was born in Wuhu, China, in 1962. He received B.S. degree from Beijing University of Aeronautics and Astronautics in 1982, M.S.E.E. and Ph.D. degrees from University of Minnesota in 1986 and 1988, respectively. Since 1990, he has been with Louisiana State University where he is currently Mark and Carolyn C. Guidry Distinguished Professor in Electrical and Computer Engineering. He is the leading author of two books in the field: Robust and Optimal Control (Prentice Hall, 1995), which has been used worldwide as graduate textbook and research references and has been translated into Japanese (1997) and Chinese (2002), and Essentials of Robust Control (Prentice Hall, 1997). He is/was an Associate Editor of Automatica, IEEE Transactions on Automatic Control, SIAM Journal on Control and Optimization, Systems and Control Letters, Journal of System Sciences and Complexity, andJournal of Control Theory and Applications. He was named the Oskar R. Menton Endowed Professor in 1998 and Voorhies Distinguished Professor in 2004, recognized for outstanding accomplishments and contributions to LSU by the House of Representatives of the Louisiana Legislature in 2004, and
