I am an Assistant Professor at the University of California Santa Cruz. In Spring 2023, I will be a CRM-Simons Scholar at the thematic program Geometric Group Theory at the Centre de Recherches Mathématiques in Montréal. Previously I was an L.E. Dickson Instructor at the University of Chicago, and a Research Member at the MSRI program Random and Arithmetic Structures in Topology. I completed my PhD at McGill University in 2018, under the supervision of Piotr Przytycki and Daniel Wise.

My research is in geometric group theory. I am particularly interested in non-positive curvature, cube complexes, Artin groups, Coxeter groups, random groups, small cancellation theories, separability properties, algebraic fibering and coherence.

I am supported by NSF grant DMS-2203307 and and NSF CAREER grant DMS-2238198.
