About Me

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 2019. My research interests are text mining and text-rich network mining.

Prior to UIUC, I received my B.Sc. degree in Computer Science from Peking University in 2017, advised by Prof. Yan Zhang.

In summer 2021, I interned at Microsoft Research Redmond (virtually), working with Dr. Iris Shen.

In summer 2020, I interned at Microsoft Research Redmond (virtually), working with Dr. Iris Shen and Dr. Yuxiao Dong.

In summer 2016, I visited Carnegie Mellon University, working with Prof. Kathleen M. Carley.

For further information, please see my CV.

Miscellany

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.
