Theo Johnson-Freyd

I am a postdoc in the Mathematical Physics group at the Perimeter Institute for Theoretical Physics. I focus on topological and conformal field theory, categories, homotopical algebra, and quantization of gauge systems, with side interests in Poisson and symplectic geometry, Lie and quantum groups, and low dimensional topology.
