Current Research


My current research interests involve searches for Supersymmetry and physics beyond the Standard Model. If we were to discover such decays, it would have a profound impact on understanding the origins of mass as well as problems such as Dark Matter. My research takes place primarily at the ATLAS detector, which is one of the experiments at the LHC (Large Hadron Collider).

I am also interested in the connection between cosmology and particle physics. I am participating in the Large Synoptic Survey Telescope (under construction at the University of Arizona) to better understand the underlying mechanisms of dark energy. Our efforts include construction of the LSST camera and studies to determine the limitations of the LSST dark energy measurements.

My previous interests revolved around the study of of CP and CPT violation. CP violation was first discovered in 1964, yet its origins remain a mystery even today. In order to explain the predominance of matter over anti-matter in the universe, some level of CP violation is required. There are two forms of CP violation, indirect and direct. My work on the KTeV experiment involved the search for evidence of direct CP violation. In 1999 our experiment established the existence of direct CP violation.
