Welcome! I am an Assistant Professor in the School of Information and Library Science, University of North Carolina at Chapel Hill. I received my PhD degree in Computer Science and Engineering from the University of Michigan. I received both my undergraduate and master's degrees from the School of Information Security Engineering, Shanghai Jiao Tong University, and a dual master's degree from the School of Electrical and Computer Engineering, Georgia Institute of Technology.
I am broadly interested in text data mining, including related areas such as machine learning, information retrieval, natural language processing, information and social networks, and health informatics.
Discovering reliable knowledge and new insights from massive data sets requires significant human efforts. My research develops principled interactive machine learning algorithms to minimize data scientists' efforts in producing high-quality results. These algorithms have been applied to a wide range of data mining tasks, including high-recall information retrieval, computer-assisted content analysis, clinical natural language processing, and aggregated web search.
