Theoretical physicist.
Postdoc at the Mathematical Institute, University of Oxford.
I work with Feynman graphs, combinatorics of power series, resurgence theory, and do a lot of C++ programming.
My goal is to understand the physical properties of renormalized Green functions in quantum field theory.
Has anyone seen an instanton around here lately?
