Xi-Ren Cao received the M.S. and Ph.D. degrees from Harvard University , in 1981 and 1984, respectively, where he was a research fellow from 1984 to 1986. He then worked as a principal and consultant engineer/engineering manager at Digital Equipment Corporation, U.S.A, until October 1993. Since then, he is a Professor of the Hong Kong University of Science and Technology (HKUST), Hong Kong, China. He is the director of the Center for Networking at HKUST. He held visiting positions at Harvard University , University of Massachusetts at Amherst , AT&T Labs, University of Maryland at College Park , University of Notre Dame, Tsinghua University , University of Science and Technology of China, and other universities .
Dr. Cao owns three patents in data and tele-communications and published two books: “Realization Probabilities - the Dynamics of Queuing Systems,” Springer Verlag, 1994, and “Perturbation Analysis of Discrete-Event Dynamic Systems,” Kluwer Academic Publishers, 1991 (co-authored with Y. C. Ho). He is a Fellow of IEEE, Chairman of the IEEE Fellow Evaluation Committee of the IEEE Control Systems Society, Editor-in-Chief of Discrete Event Dynamic Systems: Theory and Applications , Associate Editor at Large of IEEE Transactions of Automatic Control, member of the Board of Governors of IEEE Control Systems Society , member of IFAC Technical Board, and chairman of IFAC Coordinating Committee on Systems and Signals . He has been served as associate editor of a number of international journals and chairman of a few technical committees of international professional societies. His current research areas include discrete event dynamic systems, stochastic learning and optimization theory, performance analysis of communication systems, and signal processing.
