I am a postdoctoral assistant professor in mathematics at University of Michigan, Ann Arbor. I work with Alexander Perry. I completed PhD in University of Illinois Chicago. My advisor was Izzet Coskun. My undergraduate study was at Nanjing University.
I am on the job market in Fall 2026. This is my research statement.

I am interested in algebra and algebraic geometry. Specifically, my interests include (but are not limited to): Derived categories of projective varieties and quivers, DG (and A-infinity) algebras, Bridgeland stability, (DM) stacks and their derived categories, twisted sheaves and Brauer groups, stable sheaves and their moduli spaces, Brill–Noether theory, and classical low-dimensional algebraic geometry.

Currently, I am thinking about several questions about finite-dimensional DG algebras. Recently, I also grow more and more interested in Frobenious morphism (and related phenomenon) in positive characteristics.
