Chenxi Wu

Chenxi Wu serves as an Assistant Professor of Mathematics at the University of Wisconsin-Madison, maintaining his academic office at 517 Van Vleck Hall. His institutional affiliation with the Mathematics Department is evidenced by his math.wisc.edu email domain and teaching responsibilities in advanced mathematical courses, though the specific school structure is not explicitly documented in available sources.

His academic credentials include:

• Doctor of Philosophy (Ph.D.) in Mathematics, Cornell University, completed August 2016

Wu's research program centers on the intersection of dynamical systems and geometric topology. He investigates fundamental properties of ergodic theory and symbolic dynamics, exploring statistical behaviors in chaotic systems. His work extends to complex and arithmetic dynamics, examining rational function iterations in complex and number-theoretic contexts. A significant portion of his scholarship addresses mapping class groups and Teichmuller dynamics, analyzing moduli space geometries and surface homeomorphisms. He further develops these concepts for big mapping class groups of infinite-type surfaces and graphs, while applying tropical geometry techniques to dynamical problems.

Analysis of his 15 most recent publications (2019-2025) reveals consistent contributions to geometric group theory and dynamics, with emphasis on asymptotic translation lengths, stretch factors, and Master Teapot structures. His collaborative research appears in premier journals including Transactions of the American Mathematical Society and Advances in Mathematics, demonstrating interdisciplinary reach from pure mathematics to computational biology applications.

No scientific awards or major honors are documented in the provided materials.

Wu actively mentors students through graduate courses such as Ergodic Theory (Math 758) and Differentiable Manifolds (Math 761), though specific Ph.D. advisees are not listed. His teaching portfolio spans undergraduate calculus to advanced algebra, supported by comprehensive lecture notes covering 14 courses. Outreach involvement includes the Madison Math Circle and Math Explorer's Club, reflecting commitment to mathematical education beyond the university curriculum.
