Research Interests

My research interests are in high-energy particle physics, especially in experiments at colliding-beam accelerators. Our Carnegie Mellon University group is part of a large international collaboration that has constructed and is operating the Compact Muon Solenoid (CMS) experiment at the Large Hadron Collider (LHC). The LHC is a proton-proton colliding-beam accelerator at the European center for high-energy physics, CERN, in Geneva, Switzerland. It has reached center-of-mass collision energies of 13 TeV, the highest ever created in an accelerator.

Following the recent discovery of the long-sought-after Higgs boson by the CMS and ATLAS experiments, the main goals of CMS include precision measurements of the properties of the Higgs boson and searching for Physics Beyond the Standard Model. Such new physics might manifest itself through supersymmetry, dark-matter candidate particles, or additional quarks and leptons beyond the known three families. This latter aspect of searches is a specific focus of mine.
