I taught and researched in Sun Yat-Sen University, Shantou University (China), Bath University (UK), National University of Singapore, Institute of Microelectronics (Singapore), and Institute for Infocomm Research (Singapore). In February 2007, I joined the faculty of Nanyang Technological University. I am a Fellow of IEEE, a Fellow of IET, a Chartered Engineer, and Honorary Fellow of SIET.

My additional duties include serving as an Associate Editor for IEEE Trans. on Image Processing, and IEEE Trans. Circuits and Systems for Video Technology.

My research deals with image processing, perception-based modeling, video compression, and multimedia communication. I believe that good theory is practical and effective teamwork can achieve the goal of "1+1>2"; I have kept a balance of academic research and industrial deployment (and even some business development) in my working life, and also managed over ten successfully-delivered major projects for external customers.

It has been my good fortune to have the chances to work with many colleagues and students in various organizations. I always look forward to collaborating with more researchers who think alike, and am eager to meet new students with an interest in image processing, communication and understanding, as well as modeling the relevant physiological and psychological findings.
