I am an associate researcher in Microsoft Research Asia. I obtained my Ph.D. degree from School of EECS, Peking University, China. Before this, I got my Bachelor's degree in Mathematics from Beijing Normal University, China. I'm interested in deep learning, reinforcement learning, statistical topic modeling, with their applications in natural language understanding, information network analysis and information retrieval. My work on topic modeling won the best paper award in ICML 2014. Currently, I am particularly interested in learning data representations of natural languages and information networks with deep learning techniques. I'm looking for highly motivated students to work with me as interns or external collaborators. Students who are interested in working with me please send me your resume. Research Interest Deep learning, reinforcement learning, statistical topic modeling, natural language processing, network analysis, information retrieval
