Rate My Professor Andrew Zimmer

Zimmer's research accomplishments have been honored with the 2022 Alfred P. Sloan Research Fellowship, the 2020 NSF CAREER Grant, the 2014 NSF Postdoctoral Fellowship, a 2025 NSF Standard Research Grant, and roles as co-PI on NSF grants including a 2023 RTG grant and a 2023 conference grant. In 2026, he will serve as Research Professor at SLMath's semester program on Geometry and Dynamics for Discrete Subgroups of Higher Rank Lie Groups. His publications include "Rigidity of proper holomorphic maps between balls with Hölder boundary regularity" (2026, submitted, with K. Huang, J. Park, A. Skenderi, J. Srimurthy, R. Wen), "A rigidity theorem for complex Kleinian groups" (2025, submitted, with R. Canary, T. Zhang), "Weakly holomorphic homogeneous regular manifolds" (2026, Journal of Geometric Analysis), "Patterson–Sullivan measures for transverse subgroups" (2024, with R. Canary, T. Zhang), and "Bi-Lipschitz rigidity of discrete subgroups" (2024, submitted, with R. Canary, H. Oh). Zimmer has mentored postdocs such as Max Lahn and Feng Zhu, Ph.D. students including Vicky Wen and Aleksander Skenderi, and undergraduates via MXM Lab projects and REUs, with one REU project yielding a publication. He has organized workshops including the Midwest Summer School in Geometry, Topology, and Dynamics (2025), the Junior Workshop in SCV (2024), and conferences such as Gromov Hyperbolicity and Negative Curvature in Complex Analysis (2021). His teaching includes Math 421 (Theory of Single Variable Calculus), Math 765 (Differential Geometry), Math 823 (Advanced Topics in Complex Analysis), and Math 826 (Advanced Topics in Functional Analysis and Differential Equations).
