After receiving Ph.D. degree, he joined Microsoft Research Asia (MSRA) as a researcher. He was a senior researcher and group manager of the Web Search and Mining Group at MSRA since 2008. In the 14 years at MSRA, he has filed 50+ U.S. patents in Web search and related areas. Many of his research results have been integrated into important Microsoft products (e.g. Bing). His group has developed influential Web applications such as Microsoft Academic Search (http://academic.research.microsoft.com), Renlifang (http://renlifang.msra.cn/), Microsoft Product Search, etc. He has published extensively on prestigious international conferences and journals.
