Dr. Chan joined the Department of Electronic Engineering, the City University (Polytechnic) of Hong Kong in 1988 as a Lecturer. He is presently an Associate Professor of the same department. Apart from his normal teaching duties he was consultant to the Hong Kong Radio Paging Association, Member of OFTA's Radio Spectrum Advisory Committee and has performed consultancy projects with companies that include the MTR, KCR and HKO. He was also the past Chairman of the IEEE AP/MTT Chapter, HK Section.


Previous Experience 1984 - 1988, Senior Engineer, Microwave Engineering Designs Limited. One of the four founding members specializing in RF/Microwave consultancy.
1982 - 1984, Engineer, Plessey RADAR. Design of various microwave components and sub-systems, which were to form part of the world's first solid-state radar transmitter at s-band.
