Over the past 20 plus years, I have carried out research in experimental high energy physics. The research has been performed at two of the premier high energy physics laboratories in the world, Fermilab near Chicago and the CERN laboratory near Geneva, Switzerland. Currently I am a member of the DØ collaboration,one of two research groups that use the Fermilab Tevatron, currently the world's highest energy particle collider. The goal of the research is to study all aspects of proton/anti-proton collisions. This includes studying particles that are produced in these collisions, such as the top-quark, and refining previous measurements to set limits on how well the standard model of particle physics agrees with data. These measurements will ultimately lead to extensions of the standard model, which should help answer such questions as the origin of mass and the asymmetry between matter and anti-matter in the universe, among many others.
At the present time, I am participating in measurements of top-quark production and using these measurements to set limits on the existence of Higgs particles that may exist in extensions to the standard model of particle physics. In the past I have carried out physics analyses that involve QCD (strong interactions) and electroweak interactions.
With the start up of the Large Hadron Collider at the CERN laboratory, I have begun to move my research effort to exploring the data that will be made available in the near future using the ATLAS detector. For the moment my plan is to extend the research that I am currently carrying out at Fermilab using the top-quark as a probe of the standard model of particle physics.
