I am currently a fourth year PhD student at the Department of Computer Sciences, UW-Madison. I am fortunate to be advised by Jelena Diakonikolas. Earlier, I received my BS in Mathematics from Zhiyuan Honors College at Shanghai Jiao Tong University.
My research interests are in the interplay between optimization and machine learning.
