My research concentrates on energy frontier physics using the CMS detector at the LHC, and particularly searches for physics beyond the Standard Model. My current interest is in models of supersymmetry that do not assume R-parity conservation, where there remains vast parameter space that has yet to be explored. Our work on R-parity violating SUSY benefits from close collaboration with Cornell theorists, who are responsible for some of the important contributions in this area.

I direct the Center for Bright Beams (CBB), which is a new NSF Science and Technology Center led by Cornell. CBB aims to increase the brightness of electron beams to open new realms in research and advance manufacturing and medicine by taking an interdisciplinary approach to overcoming today’s barriers. It is a collaborative effort that currently involves seven colleges and universities and close collaboration with national labs and industry.
