I am an Assistant Professor at the University of California Santa Cruz. I spent Spring 2023 as a CRM-Simons Scholar at the thematic program Geometric Group Theory at the Centre de Recherches Mathématiques in Montréal. From 2018 to 2021, I was an L.E. Dickson Instructor at the University of Chicago, and in Fall 2020 I was 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.

I will be spending the academic year 2024/25 at the Institute for Advanced Study as a von Neumann Fellow.

My research is in geometric group theory and low-dimensional topology. 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 the grants: NSF DMS-2203307 and NSF CAREER DMS-2238198.

CV, Research Statement

In the academic year 2023/24 I am a TLC Faculty Fellow and a Pre-tenure Faculty Writing Fellow.

In 2023/24 I co-organized the Highway CA-17 Groups, Geometry, and Topology Seminar.
