I am a second-year Ph.D. student in the Department of Biomedical Informatics of Columbia University. My advisor is Prof. Noémie Elhadad.

I received my B.E. degree in computer science from Shanghai Jiao Tong University. I was a member of the ACM Honored Class. In my undergraduate years I have been fortunate to work with Prof. Hai Zhao on natural language processing.

I visited the Natural Language Computing Group, Microsoft Research Asia as an intern in 2010, and was working in Natural Language Processing Group, Microsoft Research, Redmond, WA as a summer intern in 2012.

Research summary

An overall goal of my research is bridging the chasm between computer science techniques and biomedical practice. General natural language processing and data mining algorithms are revised to be utilized in biomedical settings. My research interests also include foundational issues in machine learning and natural language processing.
