Job opportunities

There is one postdoc position available under my grant. It is a two-year position with a possible third year extension. There is no teaching obligation. If you are interested, please send me your CV and research statement. Other application materials (e.g., letters of recommendation) can be arrange afterwards.

Research Interests

My field of research interest is in representation theory, including its connections with geometry, combinatorics, and categorification. Here is my CV.


2020 Chevalley Prize in Lie theory (joint with Weiqiang Wang).
