About

Dr. Nan Duan (段楠) joins the Natural Language Computing (NLC) group at Microsoft Research Asia from Feb. 2012. He received his Ph.D. from Tianjin University, supervised by Dr. Ming Zhou. His research interests include open domain question answering, semantic parsing, paraphrasing, knowledge mining, statistical machine translation, and their applications in building various artificial intelligence engines, such as Microsoft Xiaoice.
