I am am an NSF Postdoctoral Fellow at the University of Bristol working with Mark Hagen. Previously, I was a postdoc at Technion working with by Nir Lazarovich and Michah Sageev. I completed my PhD at McGill, where I was fortunate to be advised by Piotr Przytycki and Dani Wise.
I study geometric group theory, and I am particularly interested in cube complexes, small-cancellation theory, and combinatorial nonpositive curvature.
