I am an Assistant Professor in the Department of Industrial and Operations Engineering at the University of Michigan.

Previously, I was a postdoctoral researcher at the University of Pennsylvania, advised by T. Tony Cai and Hongzhe Li. I obtained my Ph.D. in Electrical Engineering at Princeton University in 2021, advised by Yuxin Chen and H. Vincent Poor. I have also worked with Sergio VerdĂș at Princeton. Prior to this, I received my B.E. in Electronic Engineering from Tsinghua University in 2016.

I am broadly interested in theories and algorithms for mathematical data science, high-dimensional statistics, optimization and machine learning.

I am recruiting motivated Ph.D. students interested in statistics, optimization and machine learning. If you are interested in working with me, please send me an email with your CV.
