I am a Ph.D. candidate in the School of Information at University of Michigan. I am fortunate to be advised by Prof. Qiaozhu Mei and be a member of the Foreseer Group. Previously, I received my bachelor degree in Computer Science from Peking University, with a double major in Economics.

I am passionate about large-scale behavior data analysis. I use multi-disciplinary methodologies featuring machine learning, causal inference, and experimental design. I am interested in the applied area of data science such as computational social science, social good, recommender systems, social and information network analysis.

I am looking for tenure-track positions in academia. Here is my CV.
