General Information

I obtained my bachelor's degree from Tsinghua University in 2001 and my PhD from National University of Singapore in 2006. During July to September 2004, I spent three months at AT&T labs-research in New Jersey as an intern. During March to May 2005, I spent three months at Microsoft Research in Redmond, Washington as an intern. From January 2007 on, I have been a lecturer in the Department of Computer Science and Software Engineering at The University of Melbourne. My research interest is data and information management in general, particularly in areas of indexing techniques, moving object management, web services, data streams and sequence databases.
