Dr. Fatiha Benmokhtar is an experimental particle Physicist who studies the internal structure and dynamics of strongly interacting matter with fixed target electron scattering experiments. She carries her research work at the Department of Energy’s Thomas Jefferson National Accelerator Facility ( a leading user facility in electron laser beams. Specifically, Dr. Benmokhtar investigates elementary quark, anti-quarks and gluons that constitute matter, short range correlations in light nuclei and the Physics beyond the Standard Model with high precision parity violation measurements.

Students are deeply involved in this research through software development and data analysis at Duquesne University and hardware work, and high tech electronics tests at Jefferson Lab and other laboratories worldwide.
