My research is in theoretical high energy physics, with the emphasis on the non-perturbative properties of quantum field theories such as SU(N) gauge theories. My approach to solving these theories is primarily via the computer simulation of the corresponding lattice field theories.

Theoretical Elementary Particle Physics. I use lattice field theory to calculate and understand the non-perturbative physics of quantum field theories in various dimensions. My recent research has involved the calculation of the spectrum and topological content of SU(N) gauge theories, as well as the spectrum of the confining flux tubes. We use this spectrum to determine the action of the effective string theory describing these string-like flux tubes, particularly in the important limit of N going to infinity.
