- Research Interests: Experimental Nuclear
My research is focused on precision measurement of fundamental properties of nucleons.
These studies seek to understand the internal structure of hadrons in terms of the
underlying quark and gluon degrees of freedom of Quantum Chromodynamics (QCD).
Most of this research is carried out at Jefferson Lab (JLab) in Newport News where we
undertake experiments in search of signatures of QCD in nuclei. Recently, we completed
the PRad experiment which aims to measure the
proton charge radius with sub-percent precision. The PRad experiment may help resolve the large
discrepancy between measurements using electrons vs muons (
the so called proton radius puzzle ). Another recently approved experiment involves measuring the
mesonic content of the nucleon using deep-inelastic scattering with spectator tagging, this experiment will
also allow us to exact the quark distributions inside pions.
My research program also includes precision tests of fundamental symmetries and the
Standard Model, which constitute experimental searches for new forces beyond the four included in the Standard Model.
One of these experiments (The QWeak experiment) used parity violating
electron scattering from the proton to perform the first high precision measurement of the weak charge of the
proton. As part of this experiment my group built a set of diamond micro-strip tracking detectors which were the
first such detectors to be used in a nuclear and particle physics experiment.
Another experiment is the new search for the neutron electric dipole moment (The nEDM
Experiment) which is proposed for the Spallation Neutron Source at Oak Ridge National Lab. The goal of this experiment is a factor of 100
improvement over the current experimental limit. This search for a
non-zero value of the neutron EDM is a direct search for violation of
the time reversal symmetry (T).
