Research Interests:

Theoretical Nuclear and Particle Physics

My research lies at the interface of nuclear and particle physics. In particular, I study the discrete symmetries C, P, T -- and the manifestations of their violation -- in the structure and interactions of hadrons. 

In order to expose the mechanisms that could help explain the vast preponderance of baryonic matter over antimatter in the cosmos, and possibly its dark matter, members of my research group and I are also working towards new paths of identifying new sources of matter-antimatter (CP) symmetry violation as well as of baryon number nonconservation. 

The interpretation of precision, low-energy measurements of hadronic processes to infer the existence of emergent, high-energy phenomena can require quantitative assessment of the Standard Model contributions. Thus I am also interested in improving our understanding of the non-perturbative dynamics of the strong interaction, particularly as it impacts the reliability of such predictions.

I am also interested in new ways by which terrestrial experiments can probe the nature of dark matter. This interest has spawned "data mining" projects to investigate the local structure of the Milky Way and concomitant astrophysical constraints on its dark matter.
