I am a theoretical physicist studying Quantum Field Theory. Quantum Field Theory is an exceptional framework for fundamental physics, that has had many empirical successes. But I study the challenging problems that arise when we try to actually compute the physical observables of Quantum Field Theory, as well as also its close cousin, String Theory. By resolving these problems, we can better understand the underlying physics of fundamental particles, that is otherwise obscured by our current theories. This is especially relevant for physical processes involving strongly coupled particles (quarks and gluons) or large numbers of particles. My work on these issues involves methods from modern particle theory, but also has deep connections to ongoing work in algebra, topology and combinatorics.

At Merton, I give tutorials on General Relativity and Cosmology, having previously also taught Quantum Mechanics, Special Relativity, and Mathematical Methods.
