Theo Johnson-Freyd

I am an assistant professor in Mathematics at Dalhousie University, with a joint appointment to the Perimeter Institute for Theoretical Physics. I focus on "homotopical physics": the interplay between mathematical physics (particularly quantum field theory) and higher (aka categorical) algebra. Other buzzwords that describe my work: higher symmetries, topological field theory, phases of condensed matter, "moonshine" phenomena, perturbative quantization, categories, representation theory, and algebraic topology.
