About me
I am currently a PhD student at the Department of Electrical, Computer, and Systems Engineering, Rensselaer Polytechnic Institute, and am fortunately advised by Prof. Tianyi Chen. Prior to that, I was a visiting student at Data and Computer Science Department of Sun Yat-Sen University during 2020-2021, hosted by Prof. Qing Ling. Previously, I obtained my B.S. degree of Statistics from University of Science and Technology of China in 2020.
Research interests: bilevel optimization, distributed optimization, and statistical signal processing.
