I am now a researcher at Microsoft Research AI. Before 2018, I was a Ph.D. student at Language Technologies Institute (LTI), Carnegie Mellon University. I came to LTI in 2012 fall as a master student in the Master in Language Technologies (MLT) program, and started in the Ph.D. program of LTI in 2014 fall. I expect to graduate in Summer 2018 and am going to join MSR AI as a researcher, starting Fall 2018.

Before coming to the US, I completed my undergraduate study at Wuhan University, China in 2009, and got a master degree at Institute of Software, Chinese Academy of Science, at 2012.

Research Interests

My research interests fall in the intersection of information retrieval, semantics, and machine learning. My dissertation research's goal is to improve text representation and understanding with discrete semantics from knowledge graph and distribution semantics using deep learning.

My dissertation topic is "Knowledge Based Text Representations for Information Retrieval", proposed in May 2016 [pdf] [slides]. I successfully defended in August 2018[pdf] [slides]. My committee includes Jamie Callan, William Cohen, Tie-Yan Liu, and Bruce Croft.
