I am Xingzhe Li (in Chinese: 李星哲), a fourth-year graduate student in Mathematics at Cornell University. My advisor is Prof. Xin Zhou. I am currently on the market for postdoc positions starting in the Fall of 2026.
I got my BS in Mathematics (with Highest Honors) from UC Santa Barbara. My undergraduate advisor is Prof. Fedor Manin.
Research Interests
My research primarily lies in Differential Geometry and Geometric Analysis. Recently, I have focused on adapting variants of Simon-Smith min-max theory to show the existence of minimal surfaces with controlled topological type in complete three-manifolds. Besides this, I am keen on exploring the connections among minimal surface theory, geometric group theory, and representation theory.
