About
I am an Assistant Professor at The Hong Kong Polytechnic University, Department of Data Science and Artificial Intelligence.
Prior to joining PolyU, I was a Research Assistant Professor in the Department of Statistics at The Chinese University of Hong Kong. I received my Ph.D. in Mathematics from Hong Kong University of Science and Technology in 2020 and my bachelor's degree in Pure Mathematics and Applied Mathematics from Sichuan University in 2016.
My research interests span high-dimensional statistics, ranking, online inference and reinforcement learning.
