I am currently a visitor at Cornell University.

In case you want to reach me in Chinese, my name is 李冠宇.

I am interested in applying methods from homological and homotopical algebra to problems in algebra, algebraic geometry, representation theory, and number theory. I am also interested in the aspects of algebraic topology that interact with these methods. 

I obtained my Ph.D. at Cornell University, under the supervision of Yuri Berest.

Here is my CV (last update: Mar, 29, 2025).
