Research interests

Nucleon structure: Involved in a series of measurements of nucleon structure via 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. Have follow-up measurements approved at Jefferson Lab and Novosibirsk to study the effect of two-photon exchange corrections to the form factors. 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, focusin 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

Color Transparency: Involved in SLAC and JLab studies of color transparency in A(e,e'p) reactions, the recent JLab Hall B measurement of color transparency in rho electroproduction, and JLab Hall C measurement of transparency in pion electroproduction.

The majority of my work is performed in Hall C and Hall A at Jefferson lab, though I am (or have been) involved in Hall B experiments as well as experiments at MIT-Bates, SLAC, HERMES at DESY, Fermilab, and Novosibirsk.
