Associate Professor
Brandon Seward is an Associate Professor of Mathematics at the University of California San Diego (UC San Diego), where they conduct research and teach in the Department of Mathematics. They use the pronouns they/them or he/him . Education Ph.D. in Mathematics, University of Michigan , 2015 Research Interests Their work lies at the intersection of ergodic theory, topological dynamics, descriptive set theory, and group theory . They investigate geometric, combinatorial, and entropic properties of actions of countable groups, with special emphasis on the divide between amenable and non-amenable groups. Publications & Research Impact Across 27 refereed papers (2014-2024), Seward has advanced entropy theory for non-amenable groups, Borel combinatorics of group actions, and structure theorems for measure-preserving actions. Their work has appeared in top journals such as Inventiones Mathematicae , Journal of the American Mathematical Society , and Duke Mathematical Journal . Scientific Awards Michael Brin Dynamical Systems Prize for Young Mathematicians (2018) – awarded for outstanding contributions to dynamical systems. Teaching & Mentorship Seward regularly teaches core undergraduate courses (e.g., Math 142A Introduction to Analysis) and organizes the UC San Diego Group Actions Seminar , a weekly research forum featuring international speakers. They serve as a faculty mentor and are actively involved in graduate student supervision and seminar coordination.
