I was born and raised in China where I obtained a B. Comp. (Hons 1st Class) from Shanghai Science and Technology University in 1998 and a Master degree in Computer Science from Shanghai Jiao Tong University in 2001. I was conferred a PhD degree in Computer Science at National University of Singapore (NUS). My advisor at NUS was Prof. Ling Tok Wang. I did my Postdoc research with Prof. Chen Li in the Department of Computer Science, University of California, Irvine. I joined Renmin Univesity of China in June 2008.
I am looking for new Master students. Please contact me if you are interested. See details.
If you are an undergraduate in the final year and interested in working with me,
please click here to see the details about our project "Approximate keyword search in advanced Search Engine".
Research Interest
My research interests are in the fields of database and information systems, including XML query processing, personal information system, XML keyword processing and query refinement, approximate string matching, cloud data management.
News
- ICDE 2009 accepted paper: Our two papers "Effective XML Keyword Search with Relevance Oriented Ranking" [pdf] and "Space-Constrained Gram-Based Indexing for Efficient Approximate String Search" have been accepted as long papers by the 25th IEEE Intl Conference on Data Engineering (ICDE) 2009, to be held in Shanghai, China.
- I will give a panel talk titled "Review of Claremont Report on Database Research" at National Database Conference 2008, Guilin China. [slides ]
