I am a Ph.D. student in the Data Mining Group at University of Illinois at Urbana-Champaign, advised by Prof. Jiawei Han. I finished my M.Sc. study in the same group in Spring 2019. My research interests are text mining, information network analysis, and their applications to bioinformatics.

Before joining UIUC, I received my B.Sc. degree in Computer Science from Peking University in 2017. During my junior and senior years, I was a research assistant at Data Analysis and Intelligent Retrieval Lab, supervised by Prof. Yan Zhang.

During Summer 2016, I spent two months as a summer intern at Carnegie Mellon University, working with Prof. Kathleen M. Carley and Dr. Wei Wei.

I was born and raised in Shanghai.

I like taking MOOCs when I intend to learn something as a beginner. Some MOOCs I have finished: Networks (2015-04), Model Thinking (2015-05), Probability (2015-05), Economics (2018-08).

I played bridge during my high school and undergraduate time. Sometimes I could get a good place.
