Biography
I am a Visiting Assistant Professor in the
Department of Computer Science and Engineering
at the Hong Kong University of Science and
Technology.
I received my M.Sc. (2004) and Ph.D. (2010) degrees in Computer Science and Engineering from the
Hong Kong University of Science and Technology, and
my B.Sc. (2002) degree in Computer Science from the
University of British Columbia, Canada. A copy of my CV is available here in pdf format.
Research Interests
