Research Interests:

I study the properties of strongly-interacting systems, most of which appear in the context of elementary particle physics, with a combination of analytic and numerical techniques.

I am interested in the physics of strongly interacting quantum fields. The prototype of such system is Quantum Chromodynamics, the theory of quarks and gluons which describes the strong nuclear force. Succesful calculations in this area of science predict (or postdict) the properties of strongly interacting particles like the proton in terms of the properties of its constituents and of their interactions. Lately I have begun to apply these techniques to conjectured models of new physics beyond the Standard Model, which might be observed at the Large Hadron Collider. I use a mix of analytic techniques and numerical simulation on small and large computers in my research. In addition, I have an amateur interest in all areas of theoretical physics.
