I have been an assistant professor in the Department of Computer Science and Engineering at the Ohio State University (OSU) since Fall 2016. Prior to that, I spent half a year as a visiting scientist at the University of Washington, and received a Ph.D. in Computer Science from University of California, Santa Barbara (2015) and a B.S. in EEIS from the University of Science and Technology of China (2010).

Check out my awesome group!

I am looking for multiple highly self-motivated Ph.D. students and Postdocs, and also have interest in advising passionate master and undergraduate students, as well as hosting visiting students (Funding can be provided to students with great records and performance). Please do not hesitate to contact me if you are interested.

Research Interests

My research interests lie in natural language processing, data mining, and machine learning, with emphasis on natural language interfaces, text mining and understanding, network analysis, and human behavior understanding. Particularly, my research projects focus on: (1) Machine intelligent question answering (QA) based on various sources, such as knowledge bases, texts, and tables; (2) Human collaborative QA: expert behavior understanding and expertise mining; (3) Knowledge discovery from texts and networks. We aim to develop advanced models and systems that enable users to easily query big data, write compute programs, collaborate with each other, and acquire knowledge for decision making in various domains such as healthcare, education, and business. Please check out our publications by topic and group github (code & data).
