Zein-Eddine Meziani

Group Leader, Senior Physicist/Argonne Distinguished Fellow


Zein-Eddine Meziani is a Senior Scientist and Group Leader of Medium Energy Physics in the Physics Division at Argonne National Laboratory. He is on leave from Temple University where he has served as a Professor of Physics since 1993. Dr. Meziani received his Ph.D. in 1984 from the University of Paris XI, Orsay, France in experimental nuclear physics. He then joined the Nuclear Physics at SLAC (NPAS) program as a postdoctoral fellow with the University of Virginia prior to joining the faculty of Stanford University as an Assistant Professor in 1986. He joined Temple University in 1993 as an Associate Professor and was appointed Professor in 1996.

Dr. Meziani’s research centers on experimental studies of the multi-dimensional structure of nucleons and nuclei in terms of quarks and gluons within Quantum Chromodynamics (QCD) and, investigated nuclear medium effects on the nucleon electromagnetic properties and few-body nuclear systems. He has performed experiments at CEA Saclay France, SLAC, BNL, and Jefferson Lab.

Dr. Meziani was involved in the studies of the neutron spin structure at SLAC using a polarized 3He target in the early 90s and brought some of these experimental studies from SLAC to Jefferson Lab where his research flourished into some of the important science motivations of the 12 GeV upgrade of Jefferson Lab.

Dr. Meziani is spokesperson of many experiments at Jefferson Lab and was also a member of the Program Advisory Committee (2004-2007). He has served as the Chair of Jefferson Lab Users Group Board of Directors (2009-2011). In 2007 he co-chaired, the QCD and Hadron Physics Town Meeting of the APS/Division of Nuclear Physics (DNP). He was a member of the Nuclear Science Advisory Committee (NSAC) Long-range Plan Working Group in 2007 and 2014. In 2012 he was a member of the Subcommittee on Scientific Facilities of NSAC, and more recently (2017-2018), he served on the committee on a U.S.-Based Electron Ion Collider Science Assessment at the National Academy of Sciences.

Dr. Meziani is co-author of more than 130 peer-reviewed papers, Co-Editor of the European Physical Journal A (EPJA) (2007-2016) and Co-Editor of the Electron Ion Collider White Paper. Dr. Meziani is a Fellow of the American Physical Society (APS), 2004, and the recipient of the Temple University Faculty Research Award, 2008.
