My research area is in Information Retrieval, Recommendation Systems, Internet Economics, as well as Machine Learning and Data Mining ApplicationsWithin the above areas, our recent research focuses on the intersection of Economic theories, Recommendation and Search Systems, and Natural Language Processing, including 1) Internet Economics – the application and analysis of economic theories in web-based applications such as recommendation, search, and sharing economy; 2) Explainable Decision Making Systems – developing explainable machine learning theories and algorithms for decision making systems such as recommendation and search; 3) Conversational Search, Recommendation, and QA systems. My group is also broadly interested in "Personalized X", including Personalized Recommendation, Search, NLP, Education, Healthcare, Chatbots, etc.

In the previous I was a postdoc in the Center for Intelligent Information Retrieval (CIIR) at UMass Amherst, and did my PhD and BE in Computer Science at Tsinghua University, with a BS in Economics at Peking Univeristy. I am a Siebel Scholar of the class 2015, and a Baidu Scholar of the class 2014.
