Professor of Chemistry and Chemical Engineering at Virginia Commonwealth University (VCU). He received his B.S. and M.S. degrees from Cairo University, and a Ph.D. in Physical Chemistry with Distinction from Georgetown University. He did postdoctoral research in nucleation and clusters at the University of California, Los Angeles (UCLA). His research interests are in the general areas of molecular clusters, nucleation phenomena, gas phase polymerization, nanostructured materials, graphene and nanocatalysis. His current research is focused on the development of new nanostructured catalysts and novel catalytic processes for energy and environmental applications. He has published over 200 refereed papers and review chapters, and he holds eight US patents on the synthesis of nanomaterials, nanoalloys, nanoparticle catalysts, graphene, and graphene-supported catalysts. Prof. El-Shall serve on the US National Committee for the International Union of Pure and Applied Chemistry (USNC/IUPAC) and the Editorial Boards of the Journal of Physical Chemistry, the International Journal of Photoenergy, the Open Physical Chemistry Journal, Metals, and the Annual Review of Graphene.
