CHAN

CHAN, Stephen Chi-Fai (Dr.)

Associate Professor
B.Sc. (U. of Rochester), M.Sc. (U. of Wisconsin), M.Sc., Ph.D (U. of Rochester).

Research Interests:
Data Engineering, Collaborative Work, Human-Computer Interaction, Service Learning.

Dr. Chan received his PhD from The University of Rochester, where he was a member of the Production Automation Project under Professor Herbert Voelcker. He then worked on a NURBS-based surface modeling system for industrial design for Neo-Visuals in Toronto. Subsequently he became a research officer for the National Research Council of Canada on computer-integrated manufacturing and represented Canada in the development of the international product data exchange standard, STEP. He joined the then Hong Kong Polytechnic in 1993. Dr. Chan is currently looking for research assistants and students in collaborative robotics and recommender systems.

Dr. Chan is a firm believer of service learning. In addition to services in Hong Kong, he has taken students to carry out service learning projects in Hubei and Gansu in mainland China since 2006. Together with Dr. Vincent Ng and Dr. Grace Ngai, he was given the Faculty of Engineering Award (Team) in Teaching in 2007. Together with several other colleagues, he was given the President’s Award (Team) in Services in 2008.
