I am a Senior Research Scientist at EMC Research China, one of the research groups at EMC Corporation, the world's leading developer and provider of information infrastructure technology and solutions.
I received my Ph.D. degree from Renmin University
of China in 2007, under the supervision of Prof. Xiaofeng Meng.
My current research interests include personal information management and mobile information management, which addresses the question of how to adapt database techniques in a personal and mobile computing environment.
Some research results have been published in refereed international journals and conference proceedings including Geoinformatica, JCST, SIGMOD, VLDB, CIKM, MDM etc.
I have held visiting research positions at the PRISM Lab of Versailles University in Paris (2005) and Hong Kong Baptist University (2006). I have served as the program committees in international conferences including EDBT 2009, VLDB 2010, ACM CIKM 2009 Workshop on Cloud Data Management (CloudDB) and the reviewers of Journal of Future Generation Computer Systems and Journal of Systems and Software.

- iMecho - An intelligent personal search system
-- Exploit resource associations and context to enhance personal search.
-- Automatically create semantic links from explicit and implicit user activities and generate link-based ranking (e.g. pagerank-like ranking) and association graph to enhance search.
-- Automatic capture of user's context (e.g. use's current task) by tracking and analyzing user's desktop activity and then using a mathematical model (e.g. hidden markov model) to calculate relevance the access probability given the context.
