Tobias Fritz

Welcome to my page. I am a "physical mathematician" at the Perimeter Institute in Waterloo, Ontario. My scientific interests revolve around fundamental physics and its natural connections to pure mathematics and computer science. Presently, I am studying functorial quantum field theory and Higher Topos Theory. Sometimes I like to hang around on Orpheus e.V. or on the n-Category Café.
