I am an associate researcher in the Computer-Mediated Living Group at Microsoft Research Cambridge and a research fellow at Corpus Christi College in the University of Cambridge. My research is on Human-Computer Interaction (HCI). My work spans a variety of areas in HCI, such as novel interaction technologies beyond desktop computing, computer-supported cooperative activities, user performance modeling, and applications of computer vision techniques in HCI.
Before joining Microsoft, I also worked at other research labs such as in IBM, Intel, and Siemens. I received my PhD from the Department of Computer Science at University of Toronto, supervised by Prof. Ravin Balakrishnan. For earlier information please visit my my old homepage at University of Toronto.
