I am an associate professor at the University of Michigan School of Information. I received my PhD degree from the Department of Computer Science at the University of Illinois at Urbana-Champaign.
I received my Bachelor's degree from Peking University.
My major research interests include data mining and information retrieval. I am particularly interested in analyzing large scale text data, social and information networks, and user behavior data. My research is broadly applied to Web search and mining, social computing, scientific literature mining, and health informatics. I am also broadly interested in natural language processing, machine learning, and social network analysis.
