Mahmoud Sherif

Research Assistant

Mahmoud Sherif is a PhD candidate in the Department of Geological Sciences. He works with Dr. Sturchio. His research focuses on investigating radionuclide impact on quality of fossil groundwater in the Middle East. He uses stable and radiogenic isotopes in order to characterize geological and hydrogeochemical processes in aquifer systems. He also uses isotopic abundances in order to model sedimentation rates in lakes and to date ancient groundwater.
