Biography

Professor Soung Chang LIEW received his  S.B., S.M., E.E., and Ph.D. degrees from the Massachusetts Institute of Technology. From 1984 to 1988, he was at the MIT Laboratory for Information and Decision Systems, where he investigated Fiber-Optic Communications Networks. From March 1988 to July 1993, Professir Liew was at Bellcore (now Telcordia), New Jersey, where he engaged in Broadband Network Research. He is currently Professor and Chairman of the Department of Information Engineering,  the Chinese University of Hong Kong. He is also Adjunct Professor at Southeast University, China.

 

Professor Liew’s current research interests include wireless networks, Internet protocols, multimedia communications, and packet switch design. Soung and his student won the best paper awards in the 1st IEEE International Conference on Mobile Ad-hoc and Sensor Systems (IEEE MASS 2004) the 4th IEEE International Workshop on Wireless Local Network (IEEE WLN 2004). Separately, TCP Veno, a version of TCP to improve its performance over wireless networks proposed by Soung and his student, has been incorporated into a recent release of Linux OS. In addition, Professor Liew initiated and built the first inter-university ATM network testbed in Hong Kong in 1993.

 

Besides academic activities, Professor Liew  is active in the industry. He co-founded two technology start-ups in Internet Software and has been serving as consultant to many companies and industrial organizations. He is currently consultant for the Hong Kong Applied Science and Technology Research Institute (ASTRI), providing technical advice as well as helping to formulate R&D directions and strategies in the areas of Wireless Internetworking, Applications, and Services.

 

Professor Liew is the holder of three U.S. patents and Fellow of IEE and HKIE. He is listed in Marquis Who’s Who in Science and Engineering. He is the recipient of the first Vice-Chancellor Exemplary Teaching Award at the Chinese University of Hong Kong.
