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.
