Education
Prof. Hamed holds two doctoral degrees: a PhD in Hydrogeology and Geochemistry from the University of Sfax (Tunisia) in collaboration with Vienna University (Austria), and a second PhD in Nuclear Radioactivity Contamination from the University of Gabes (Tunisia) in partnership with Heifi University (China). He also earned a Postdoctoral Fellowship in Hydrogeology through the Fulbright Program at the University of Houston (USA), focusing on integrated geomorphological and geochemical analysis of karst aquifers. Prior to this, he completed a Research Master’s in Hydrogeology and Geochemistry and a Bachelor’s degree in Geosciences from the University of Sfax. His academic journey is supplemented by international certifications, including training from UNESCO-France in climate change impact and from the University of New Mexico-USA in chemical security. This robust academic foundation has enabled Prof. Hamed to conduct interdisciplinary research and provide policy-relevant environmental assessments at national and international levels.
Professional Experience
Prof. Hamed’s professional portfolio includes diverse, high-impact assignments in Tunisia, Saudi Arabia, Algeria, Iraq, and the United States. As Senior Expert, he has led extensive water quality monitoring campaigns, managed hydrometeorological networks, and conducted environmental audits for courts and ministries. In Tunisia, he headed large-scale aquifer modeling projects funded by the EU and GIZ-Germany. His expertise also contributed to evaluating oil and groundwater overexploitation impacts on subsidence in Texas, USA. He has worked on nuclear contamination assessments in phosphate mining regions and led geochemical risk analyses for both groundwater and soil. Prof. Hamed is frequently engaged by environmental ministries and international donors for projects exceeding €80 million in budget. His combined role as technical expert, field scientist, and project leader ensures science-based outcomes for sustainable water and environmental management.
Research Interests
Prof. Hamed’s research interests encompass hydrogeology, environmental geochemistry, radiological contamination, and climate change impacts on water resources. He specializes in groundwater modeling, aquifer vulnerability assessment, pollution risk analysis, and the geochemical tracing of toxic elements. His work includes artificial recharge systems using wastewater and rainwater, hydrogeophysical mapping, and ecosystem health risk evaluations. He also explores the interface of mining activities with environmental and human health hazards, particularly involving uranium and heavy metal contaminants. He integrates remote sensing, GIS, and isotope hydrology in his research and applies this to address environmental justice and water security in arid and semi-arid regions. Prof. Hamed’s work is highly interdisciplinary and policy-relevant, bridging science, public health, and environmental law. His ongoing focus includes remediation strategies for radioactively contaminated groundwater and development of sustainable desalination impact assessments.
Awards and Recognitions
Prof. Hamed has achieved top-ranking positions on national and continental scales: #1 in Tunisia and Africa, and #22 globally on the AD Scientific Index in Hydrogeology and Environmental Sciences. He is a recipient of multiple recognitions for international research leadership, including appointment as President of the International Association of Water Resources in the Southern Mediterranean Basin and Chairman of the International Symposium of Water Resources and Environmental Impact Assessment in North Africa. He has served as national and international committee member for PhD and curriculum reforms and is a trusted evaluator for major academic funding programs such as PRIMA, Erasmus+, and PHC-Maghreb. He is also Editor-in-Chief and Guest Editor for international journals such as Water, Sustainability, and Environmental Integration. These accolades underline his global standing and influence in hydro-environmental research and academic governance.
