Welcome to my homepage! I am currently a final-year PhD student in the Department of Mathematics at the Hong Kong University of Science and Technology, advised by Prof. Zhigang Bao. I have also had the fortunate opportunity to work with Prof. Qiyang Han at Rutgers University. My research interests primarily revolve around random matrix theory and high-dimensional statistics.
