I am a Research Scientist at Advanced Digital Sciences Center (ADSC). Before joining ADSC, I ever worked at the Chinese University of Hong Kong and Shenzhen Institute of Advanced Technology, Chinese Academy of Sciences. I obtained my Ph.D. degree in computer science from Queen Mary, University of London in October 2007.
