Nelson Yung received his B.Sc. and Ph.D. degrees from the University of Newcastle-Upon-Tyne. He was lecturer at the same university from 1985 to 1990. From 1990 to 1993, he worked as senior research scientist at the Department of Defence, Australia. He joined the University of Hong Kong in late 1993 as Associate Professor. He leads a research team in digital image processing and Intelligent Transportation Systems. He is the founding Director of the Laboratory for Intelligent Transportation Systems Research at HKU, and also Deputy Director of HKU’s Institute of Transport Studies. Dr. Yung has co-authored five books and book chapters and has published over 130 journal and conference papers in the areas of digital image processing, parallel algorithms, visual traffic surveillance, autonomous vehicle navigation and learning algorithms. He has one US patent and successfully transferred his research to a spin-off technology company. He regularly delivers talks/seminars to government units, professional institutions, associations and commercial companies and gives interviews to local press regarding his research. He acts as consultant to a number of local and international companies. He regularly serves as expert witness for the Courts of the HKSAR. He also serves as reviewer for the IEEE Transactions of SMC, CASVT, Vehicular Technology, Signal Processing, SPIE Optical Engineering, SPIE Journal of Electronic Imaging, HKIE proceedings, Microprocessors and Microsystems, and Robotics and Autonomous Systems Journal. He was a Member of the Advisory Panel of the ITS Strategy Review, Transport Department, HKSAR, Regional Secretary of IEEE Asia-Pacific region, Council Member and Chairman of Standards Committee of ITS-HK and Chair of Computer Division, International Institute for Critical Infrastructures. He was a Croucher Scholar and his team won the Silver Award from the Hong Kong Electronic Industry Association for Outstanding Innovation and Technology Product, 2000, for the MOVER (Mobile and Online Vending EnableR) solution. He is a Chartered Electrical Engineer, Member of the HKIE, IET and Senior member of the IEEE. His biography is published in Who’s Who in the World (Marquis, USA) since 1998, and Who’s Who in Asia.
