Jack Chou 周辰恩

Hello, my name is Jack (Chen-An) Chou. I am a first year Ph.D. student at the University of Minnesota. My research interest is in algebraic combinatorics. I especially enjoy combinatorial aspects of Schubert calculus.

Before transfering to UMN, I was a Ph.D. student at the University of Florida for two years, advised by Zachary Hamaker. Before that, I was an undergraduate at the University of California, San Diego, mentored by Brendon Rhoades.

My email address is chou0188 (at) umn.edu. My CV is here.
