I am currently a fourth year Ph.D. student at
Duke University, in the
Computer Science Department. I am fortunate to have Prof. Rong Ge as my advisor.
Broadly, I am interested in deep learning theory.
I did my undergraduate study at Shanghai Jiao Tong University (SJTU).
This summer, I am doing a research internship at Facebook AI, with Dr. Yuandong Tian as my mentor.
In fall 2019, I visited IAS for the Special Year on Optimization, Statistics, and Theoretical Machine Learning. In Spring 2017, I did an intern in the Division of Mathematical Sciences, Nanyang Technological University, advised by Prof. Xiaohui Bei.
At SJTU, I was conducting research on algorithmic game theory under the supervision of Prof. Fan Wu.
Here is my CV (last update: Sep. 2021)
