Research interests

Public Lecture: "What's the matter with matter, or: How I learned to stop worrying and love the proton"

Nucleon structure: Used elastic and inelastic electron scattering to measure the nucleon structure functions and study quark-hadron duality. Performed detailed analysis of the discrepancy between Rosenbluth and Polarization transfer measurements of the proton form factor, as well as the effects of higher-order radiative corrections (two-photon exchange and Coulomb distortion). Performed "Super-Rosenbluth" measurement to more precisely understand the discrepancy. Completed follow-up measurements at Jefferson Lab and Novosibirsk to study the effect of two-photon exchange corrections to the form factors through a precise comparison of electron and positron scattering. Examining impact of two-photon exchange in the extraction of the proton charge radius and involved in measurements to test the 'proton radius puzzle'.

Nuclear structure functions: Measured high-x scattering from nuclei, aimed at isolating the short-range structure of the nucleus and understanding modification to nucleon structure within the nuclear medium. Performed duality studies with high-precision nucleon and nuclear structure function measurements. Recently completed experiments to study Short-Range Correlations and to measure the EMC effect at large x, focusing on light nuclei. In both cases, the anomolous behavior of Be-9 suggests the importance of the alpha-like cluster structure, which appears to have a significant impact, even in high-energy scattering. These data clearly demonstrate a connection between the presence of high-momentum nucleons and the modification of the nuclear quark distributions. Given the isospin structure of SRCs, this also suggests that the EMC effect will have a significant flavor dependence in neutron-rich nuclei

The majority of my research is performed at Jefferson Lab, but I have also led or participated in experiments at MIT-Bates, SLAC, HERMES at DESY, Fermilab, PSI, and Novosibirsk.
