About me

I am a Statistics PhD student in University of Texas at Austin. I am fortunate to be advised by Prof. Stephen G. Walker. My current research mainly focuses on Bayesian statistics, especially Bayesian nonparametric methods and uncertainty quantification, and generative models. I am also interested in gradient-based methods, Monte Carlo methods, optimization and statistical machine learning.

Before moving to Austin, I received an M.S. degree in Statistics from University of Chicago in 2020, and a B.S. degree in Mathematics and Applied Mathematics from Fudan University in 2018.

In my free time, I enjoy watching movies, musicals, and traveling. So far, I’ve explored 25 countries across Asia, Europe, North America, Africa and South America (wishing for world peace). My favorite band is Coldplay, and my favorite musical is Into the Woods.
