My area of research is experimental elementary particle physics. My present interest is in experiments at the energy frontier including those that use the world's highest energy accelerators to study collisions of subatomic particles such as protons. I also have a strong interest in the development of semiconductor detectors for use in high energy physics experiments, and I am currently involved in several major efforts in the continued development of these detectors.
Over the last decade I have been working within the department's high-energy group on the development and construction of silicon pixel detectors for an experiment called ATLAS. This experiment is currently taking data at the Large Hadron Collider (LHC) that is at the European particle physics laboratory CERN located in Geneva, Switzerland. It is a multipurpose detector to study collisions between protons at a center-of-mass energy of 7 TeV. A major goal of ATLAS is to discover the Higgs particle, which is thought to be responsible for the generation of the masses of other particles according to current theory. If the Higgs particle is discovered, this will open up whole new areas of study. Our group is analyzing ATLAS data and we have presented recent results on the measurement of the top-antitop quark pair production cross section and on results of searches for supersymmetry.
The pixel detectors we helped to develop are the detector elements closest to the collision point and provide the best position measurements for charged particles produced in collisions. We are also participating in hardware improvements to the existing ATLAS detector that are under construction including another layer of silicon pixel detectors that will be added during a planned shutdown starting in 2013.
