Overview

Dr. Li is an Assistant Professor in the Department of Mathematics, Statistics and Physics at 麻豆破解版 State University. He earned his Ph.D. from University of California, San Diego in 2017, under the guidance of Professors Lei Ni and Ben Chow. Prior to his current position, Dr. Li was a Visiting Assistant Professor at the University of California, Irvine from 2017 to 2022, where he worked with Professor Richard Schoen, and he also held a Britton Postdoctoral Fellowship at McMaster University from 2020 to 2021.

Dr. Li specializes in Geometric Analysis, employing partial differential equations to investigate the geometric and topological properties of spaces such as Riemannian manifolds. His research interests include Ricci flow, Ricci solitons, 碍盲丑濒别谤-Ricci flow, curvature and topology, the curvature operator of the second kind, Einstein four-manifolds, Gauss curvature flow, modulus of continuity estimates, eigenvalue problems, heat kernels, Robin boundary conditions, matrix Li-Yau-Hamilton estimates, and parabolic frequencies.
