My current research is focused on understanding the dynamical structure of the proton. In the naive quark model, the proton consists of 3 quarks (uud). However, the proton is not a static object, but a continually changing one. Depending on how one probes the proton, strange quark-antiquark pairs and gluons can contribute to its observed properties. My current effort at Thomas Jefferson National Laboratory has been devoted to the detection of an exotic 5 quark object known as a pentaquark,named the theta+.
As Chair of the Real Photon Working Group of the Hall B Collaboration, I contribute to the planning, execution, and analysis of Hall B experiments. In order to study the properties of nucleons, much of my effort is devoted to particle detector operation and computer programming through investigations using Monte Carlo simulation, and data analysis.
