About Me

Hi! I am currently a postdoctoral researcher at Shanghai Center for Mathematical Sciences, Fudan University. I am mentored by Hehui Wu.

Before returning to my alma mater Fudan, I received my PhD degree in Algorithms, Combinatorics, and Optimization (ACO) at Georgia Institute of Technology, where I was fortunate to be advised by Anton Bernshteyn. Here’s my Math Genealogy entry.

My hometown is Dongtai.

Research Interest

My main areas of research are combinatorics and descriptive set theory. Some particular topics I am interested in : probabilistic methods in descriptive combinatorics, Markov Chain Monte Carlo, distributed algorithms.
