Biography

I have moved. This page is no longer updated. Please refer to my new homepage at: profile.synyi.com/shaodian

I was a Ph.D. student in the Department of Biomedical Informatics of Columbia University. My advisor was Prof. Noemie 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.
