I'm a professor and Canada Research Chair in Combinatorics in Quantum Field Theory in the Combinatorics and Optimization department in the Faculty of Mathematics at the University of Waterloo. My pronouns are they/them. Find my contact information here. I was previously at Simon Fraser University.
I work in combinatorics and quantum field theory and recently also causal set theory. I'm often thinking about the connection between Feynman graphs and graph polynomials, as well as the recursive structure of quantum field theory and how we can better understand it combinatorially. Lately I'm thinking more about locally finite posets. I also play with more purely combinatorial ideas like lattice path enumeration. I'm interested in anything fun.
