Hang Li
I am senior researcher and research manager of Information Retrieval and Mining Group at Microsoft Research Asia. I am also adjunct professor of Peking University, Nanjing University, Xian Jiaotong University, and Nankai University. I am co-director of the MS joint lab at PKU and member of the machine learning lab at NJU.
I joined Microsoft Research in June 2001. Prior to that, I worked at the Research Laboratories of NEC Corporation.
I obtained a B.S. in Electrical Engineering from Kyoto University in 1988 and a M.S. in Computer Science from Kyoto University in 1990. I earned my Ph.D. in Computer Science from the University of Tokyo in 1998.
I am interested in statistical learning, information retrieval, data mining, and natural language processing.
