Dr. Lamiaa El Fassi is an Associate Professor in the Department of Physics & Astronomy at Mississippi State University. Her research focuses on 1. unraveling the dynamics of strongly interacting particles, hadrons, and their elementary constituents, quarks and gluons, via the study of the hadronization and fragmentation processes that probe the dynamics of quark propagation and hadron formation in cold nuclear matter, and the color transparency phenomenon; that is, the formation and evolution of small size configurations to regular hadrons as well as deciphering the effect of in-medium modifications of the transverse momentum distributions (TMDs) in nuclei, and 2. studying the nucleon structure mainly the anti-quark asymmetry and some medium stimulated effects such as the quark energy loss and the “EMC” effect using the unpolarized Drell-Yan (DY) process as well as the study of the sea-quark Sivers functions, the poorly known gluon/Twist-3 transverse momentum distributions via the J/Ψ production, and the transverse polarization, or transversity, distribution on the polarized DY production.
