Professor Oscar C. Au received the B.A.Sc. degree from the University of Toronto, Toronto, ON, Canada, in 1986, and the M.A. and Ph.D. degrees from Princeton University, Princeton, NJ, in 1988 and 1991, respectively.
After being a Post-Doctoral Researcher with Princeton University for one year, he joined the Hong Kong University of Science and Technology (HKUST), Clear Water Bay, Hong Kong, as an Assistant Professor in 1992. He is/has been a Professor with the Department of Electronic and Computer Engineering, Director of the Multimedia Technology Research Center, and Director of the Computer Engineering Program at HKUST. He has published about 280 technical journal and conference papers. His fast motion estimation algorithms were accepted into the ISO/IEC 14496-7 MPEG-4 international video coding standard and the China AVS-M standard. His light-weight encryption and error resilience algorithms were accepted into the China AVS standard. He has four U.S. patents and is applying for more than 60 on his signal processing techniques. He has performed forensic investigation and stood as an expert witness in the Hong Kong courts many times. His main research contributions include video and image coding and processing, watermarking and light weight encryption, speech and audio processing. Research topics include fast motion estimation for MPEG-1/2/4, H.261/3/4 and AVS, optimal and fast sub-optimal rate control, mode decision, transcoding, denoising, deinterlacing, post-processing, multiview coding, scalable video coding, distributed video coding, subpixel rendering, JPEG/JPEG2000, HDR imaging, compressive sensing, halftone image data hiding, GPU-processing, software-hardware co-design, and so on speech, and audio processing.

Dr. Au is a Board of Governor Member of the Asia Paci?c Signal and Information Processing Association. He is/was an Associate Editor of the IEEE Transactions on Circuits and Systems for Video Technology, the IEEE Transactions on Image Processing, and the IEEE Transactions on Circuits and Systems, Part 1. He is on the editorial boards of the Journal of Signal Processing Systems, the Journal of Multimedia, and the Journal of Franklin Institute. He is/was the Chair of the CAS Technical Committee on Multimedia Systems and Applications, the Vice Chair of the SP TC on Multimedia Signal Processing, and a member of the CAS TC on Video Signal Processing and Communications, the CAS TC on DSP, and the SP TC on Image, Video and Multidimensional Signal Processing. He has served on the steering committees of the IEEE Transactions on Multimedia and the IEEE International Conference of Multimedia and Expo. He also served on the organizing committees of the IEEE International Symposium on Circuits and Systems in 1997, the IEEE International Conference On Acoustics, Speech and Signal Processing in 2003, the ISO/IEC MPEG 71st Meeting in 2005, the International Conference on Image Processing in 2010, and other conferences. He was the General Chair of the Paci?c-Rim Conference on Multimedia in 2007, the IEEE ICME in 2010, and the Packet Video Workshop in 2010. He received Best Paper Awards in SiPS 2007 and PCM 2007. He was an IEEE Distinguished Lecturer in 2009 and 2010, and has been a Keynote Speaker for a few times.
