Welcome to my homepage!

I am currently a tenure-track associate professor at the School of Mathematical Sciences, Shanghai Jiao Tong University.

Prior to that, I was a postdoctoral principal researcher, advised by Prof. Ruey S. Tsay, at Booth School of Business, University of Chicago. I obtained my Ph.D. in Statistics advised by Prof. Guodong Li and Prof. Wai-Keung Li, at the Department of Statistics and Actuarial Science, University of Hong Kong.

Research Interest

  • Theoretical machine learning; deep learning

Education

  • 2020. Ph.D. in Statistics, University of Hong Kong

  • 2016. B.Sc. in Actuarial Science, University of Hong Kong
