I am a lead researcher of Microsoft Research Asia (MSRA). I joined MSRA in 2012 and have been a member of Natural Language Computing (NLC) group since then. Before that, I was a joint student of MSRA and Peking University.
I obtained a B.S. in Applied Mathematics from Peking University in 2007 and earned my Ph.D. in Applied Mathematics from Peking University in 2012.
My research interests include machine learning, natural language processing (NLP), and information retrieval.
My current research focus is building conversational engines for chatbots with machine learning and NLP techniques. I have been working on single-turn conversation, multi-turn conversation, and topical deep chat since 2014. I am a key technology contributor to core chat engines of Microsoft XiaoIce (微软小冰) v2, v3, v4, and v5 and Microsoft Rinna (りんな). My recent achievement with XiaoIce team is launching a fully generative chatbot in Indonesia with full dialogue generation technologies. The chatbot now has more than 1.5million users on LINE Indonesia. To track my new progress, please visit here.
