I am an Assistant Professor in the Department of Computer Science at Wayne State University. I am interested in large-scale textual information analysis in a broad sense, including information retrieval, textual data mining and healthcare informatics. More specifically, my current research focus is on graphical models (including topic models), sentiment analysis, retrieval models for social media and computational analysis of clinical interview transcripts as well as electronic health records. I obtained a Ph.D. from the Department of Computer Science at the University of Illinois at Urbana-Champaign. At UIUC I was advised by Professor ChengXiang Zhai and was a member of the Textual Information Management (TIMan) research group. After that, I was a Post-Doctoral Fellow and Adjunct Assistant Professor at Emory University working with Professor Eugene Agichtein and Professor Hongyuan Zha at Georgia Tech.
