I'm an associate professor in the math department at Simon Fraser University. Find my contact information here.
I work in combinatorics and quantum field theory. I'm often thinking about the connection between Feynman graphs and multiple zeta values, as well as the recursive structure of quantum field theory and what we can learn from it. Sometimes this leads afield, recently to algebraic geometry and to differential equations. I also play with more purely combinatorial ideas like log concavity and recursive families of trees. I'm interested in anything fun.
