Positions currently held:
Co-convener of the CMS forward detector upgrade working group.
Principle Investigator for the Minnesota High Energy Physics Grant.
My research is at the Large Hadron Collider (LHC) at CERN in Switzerland. I work with data collected at the CMS experiment, which is one of the two large general-purpose detectors at the LHC, the other being ATLAS. CMS has now collected 20 inverse fento-barns or data at 8 TeV; that combined with earlier data taken at & TeV has allowed us to observe a new state at 126 GeV, which we have now conclusively shown to be the Standard Model Higgs.The LHC is now shutdown for two years for an upgrade so that it can run at 14 TeV, with operations restarting at the end of 2014. In this new energy regime we will be searching for evidence of physical processes beyond the standard model.
In addition to studying the physics of high energy collisions, I have an interest in the problem of particle detection and the application of new emergent technologies to experimental high energy physics. One of my research interests in this area is the production of a new type of radiation tolerant optical modulator for high speed data links. In another area I am investigating the use of Silicon Carbide for the ultra-violet light detection.
