I was involved with the CLAS Collaboration at Jeffersion Lab starting as an undergraduate at UCLA under Prof. Bernard Nefkens and Prof. John Price, now at California State Domiguez Hills. This was from 2004 to 2015 and concluded with a Post-doctoral position with Prof. Ken Hicks at Ohio University. The final analysis I performed can be found in Physical Review C and on arxiv.org. The primary focus of my work as a physicist centered around:

• Fundamental symmetries of quark interactions including charge, parity and time reversal symmetry (CPT), isospin, G-parity, chirality and flavor
• Non-perturbative QCD, quark confinement and the origin of mass
• Photoproduction of light and strange baryons

PhD Dissertation and Related Projects

My dissertation, titled Ξ Hyperon Photoproduction from Threshold to 5.4 GeV with the CEBAF Large Acceptance Spectrometer, wa completed at University of California Los Angeles under Prof. B.M.K. Nefkens on November 15, 2010.
