I am currently with the Microsoft Virtual Earth team. I finished my Ph. D. in Computer Science at the University of Minnesota in 2005, and received the B.S. degree in Computer Science at the University of Science and Technology of China, Hefei, China in 1999. My current interests include local search engine design, spatial and temporal databases, data mining, and geographic information retrieval. I was a recipient of the 2004-2005 Doctoral Dissertation Fellowship at the Universtiy of Minnesota. My research advisors were Prof. Vipin Kumar and Prof. Shashi Shekhar. I am a member of IEEE Computer Society and ACM SIGMOD.
