My research is in Experimental Particle Physics. I am currently studying data from both the DØ detector using the Tevatron collider at the Fermi National Accelerator Laboratory near Chicago and the ATLAS detector using the Large Hadron Collider (LHC) at CERN laboratory near Geneva, Switzerland. Both these machines are excellent instruments for testing the predictions of the Standard Model of elementary particles and fields and to look for experimental deviations from those predictions.
At the Tevatron my recent research has focused on testing various properties of Quantum Chromodynamics (QCD), particularly the distribution of gluons within the proton.
The LHC is now the highest energy particle collider in the world and has the potential of discovering new phenomena which may extend or supersede the Standard Model. Studies indicate that answers to fundamental questions about the nature of mass, the asymmetry between matter and antimatter, and even the particles that make up the dark matter in the universe may be discovered in the near future at the LHC.
With the discovery of the Higgs Boson at the LHC in 2012, we now must determine if there is a single standard model Higgs Boson or a family of Higgs Bosons. Using ATLAS data from the LHC I am currently involved research looking for evidence of non-standard model Higgs Bosons decaying to two leptons and two quarks. I am also studying properties of the heaviest known elementary particle: the top quark.
With the excellent performance of the LHC, the future potential for the discovery and observation of new and interesting phenomena in the field of elementary particles and fields looks extremely promising. It is an exciting time to be doing experimental physics in this field.
