Patrick C. K. Hung is an Assistant Professor at the Faculty of Business and Information Technology in the University of Ontario Institute of Technology since July 2004. He is currently cooperating with Boeing Phantom Works (Seattle, USA) and Bell Canada's Privacy Center of Excellence (Toronto, Canada) on an industrial security- and privacy-related research project respectively. Before that, he was a Visiting Assistant Professor at the Department of Computer Science in the Hong Kong University of Science and Technology in Hong Kong and a Research Scientist with Commonwealth Scientific and Industrial Research Organization (CSIRO) at Canberra in Australia. He also has prior industrial experience in e-business projects in North America and Hong Kong. From 2000 to present, Patrick has been serving as a panelist of the Small Business Innovation Research and Small Business Technology Transfer programs of the National Science Foundation (NSF) in the USA. He is an executive committee member of the IEEE Computer Society’s Technical Steering Committee for Services Computing (TSC-SC), a steering committee member of the IEEE EDOC, an associate editor/editorial board member in several international journals, and a program organizer/committee member in international conferences/workshops. He has been a book reviewer for Prentice Hall and Springer, and also a reviewer for the IEEE Transactions on Computers, the IEEE Transactions on Dependable and Secure Computing, the IEEE Transactions on Systems, Man, and Cybernetics (SMC), the Journal of Management Information Systems, the Programming .NET Web Services, the IEEE Computer magazine, the IEEE Internet Computing magazine, the Decision Support Systems (DSS), the VLDB Journal, the Journal of Electronic Commerce Research, and etc.

Patrick has a Ph.D. (completed in part-time basis) and Master of Philosophy Science, both in Computer Science, from the Hong Kong University of Science and Technology, Hong Kong. Further, he has a Master of Applied Science in Management Sciences (completed in part-time basis) from the University of Waterloo (UW), Canada. He did his Bachelor of Science in Computer Science at the University of New South Wales (UNSW), Australia. On the other hand, Patrick has been studied at CLC Japanese Language Institute at Tokyo in Japan and he got Level 2, Level 3 and Level 4 Certificate of Japanese-Language Proficiency (Administered by the Japan Foundation and Association of International Education Japan).
