Bio

I am currently a first-year Ph.D. student working with Prof. Wei Wang in the Department of Computer Science at University of California, Los Angeles. My research interests lie in Data Mining, including text mining and information network analysis.

Before I started to pursue Ph.D., I was a master student of Graph Data Management and Analysis Group at Peking University, advised by Prof. Jun Gao. I spent 6 months visiting University of Illinois, Urbana-Champaign and worked on several interesting topics in text mining, advised by Prof. ChengXiang Zhai. I got my B.S degree in Computer Science from Peking University in 2015.

In 2015 Fall and 2016 Spring, I also worked as a teaching assistant for two courses: Introduction to Database Systems(Honor Track) and Database Systems Principles and Technologies instructed by Prof. Jun Gao.

I was born and raised in Changsha.

For further information, please see my CV.
