Professor, Associate Dean of Faculty Recruitment and, Research Development

### Research

My research interests centers on the strong and weak interactions of the Standard Model. In particular, I use effective field theory techniques to study heavy quarks as a probe of these interactions, and to try to uncover physics beyond the Standard Model. I am also interested in gravitational waves, the physics of extra dimensions, supersymmetry, in matter at extreme densities, and on physics relevant to the Large Hadron Collider.
