Research interests

Experimental Study of Quantum Chromo-Dynamics (QCD) in the strong (non-perturbative) regime:

  • Nucleon structure in QCD: Nucleon form factors, flavor decomposition, spin structure, transverse momentum dependent distributions and charge symmetry.
  • Nuclear QCD: Parton energy loss, hadron formation, three-dimensional imaging of nuclei, color transparency and nuclear modification effects.
  • The majority of my work is performed in Hall B at Jefferson lab, though I am (or have been) involved in Hall C and Hall A experiments, as well as experiments at HERMES at DESY and Fermilab.
