Current Research

I'm interested in understanding how the strong nuclear force determines the structure of protons, neutrons, and atomic nuclei. My favorite to technique is to use high-energy electron scattering on fixed nuclear targets. I frequently conduct experiments at the electron accelerator at Thomas Jefferson National Accelerator Facility (JLab) in Newport News, VA and I help build large particle detectors to measure the momenta of particles emerging from collisions. My latest project was a "Backward Angle Neutron Detector" (BAND), which is currently measuring the time-of-flight of neutrons emerging from deep inelastic scattering collisions on deuterium. Through the CLAS Collaboration, I'm preparing for an upcoming run that will use a wide range of nuclear targets to answer questions about multi-nucleon correlations, short-distance nuclear forces, and the effect of the nuclear medium of quark momentum distributions.
