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 also direct the Cornell Laboratory for Accelerator-based Sciences and Education, which is the home for particle physics and particle astrophysics at Cornell, hosts the Cornell High Energy Synchrotron Source (CHESS) x-ray facility and does exciting research into the science of accelerators themselves. Recent achievements include the world's highest brightness photoinjector, record performance in the superconducting RF cavities that accelerate particle beams, and new understanding of the phenomena within low emittance electron and positron beams (low emittance = small and low divergence).

Last but not least, 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 ten colleges and universities and three national labs.
