Biography

I am currently a PhD student in the College of Computing at Georgia Tech. I am fortunate to be advised by Professor Jacob Abernethy. Previously, I obtained my Master degree from Shanghai Jiao Tong University, and a Bachelor degree from Huazhong University of Science and Technology. My research focus is on machine learning theory, especially on online decision making and Riemannian optimization.

My CV is available here.
