Dr. Chan received B.Eng. and M.Eng.Sc. degrees from The University of Melbourne in 1988 and 1990 respectively, and a Ph.D. degree from the Royal Melbourne Institute of Technology in 1994. He worked in Telstra Research Laboratories (TRL) from 1989 to 1994, where he held the position of Engineer from 1989 to 1992 and Senior Engineer from 1992 to 1994. During his stay in TRL, he worked in various sections. In 1989, he worked in the Telematic and Security Section, where he was involved in the specification and development of Telecom Australia's X.500 based Corporate Electronic Directory. From 1990 to 1994, he worked in the Network Analysis Section. The projects he has invloved include evaluating the traffic and availability performance of the Australian ISDN network, development of software tools for the analysis and design of telecommunications networks, and traffic management, in particular, real-time congestion control, in Broadband ISDN.

He joined the City University of Hong Kong in December 1994, where he is now an Associate Professor in the Department of Electronic Engineering and a member of the Teletraffics and Networking Team (TNT) of the department. His past research interests include congestion control and switch architecture for ATM networks, handoff technique and data link protocols for wireless ATM networks, optimal file placement in video-on-demand networks and TCP over wireless networks. Recently, his research interest has shifted to resource allocation and routing in ad hoc networks. Occasionally, he provides consultancy to industry, including the world-first commercial operator of video-on-demand service, and a struggling VoIP service provider. He holds two patents only.
