Fei Wei

I am currently a research fellow in the Department of Mathematics at the University of Sussex, UK. Prior to this, I worked with Jon Keating at the University of Oxford from 2022 to 2024. I was a postdoctoral researcher at Tsinghua University since 2019, and a research associate in the Department of Physics at the Harvard University from 2018 to 2019. I received my PhD from both the University of New Hampshire and the University of the Chinese Academy of Sciences.

Research interests: random matrix theory, number theory, integral systems, dynamical systems
