Dr. Yehia H. Dawood is a Professor of Geosciences at Ain Shams University, Egypt, specializing in Mineralogy, Geochemistry hydrogeochemistry, isotope and environmental geochemistry. He received his PhD in Geology from Ain Shams University, following his academic training in Earth Sciences, where he developed a strong background in geochemical and hydrochemical processes, water–rock interaction, and contaminant transport in arid and semi-arid environments. Prof. Dawood has extensive academic and research experience, with a strong record of peer-reviewed publications in international journals and supervision of postgraduate research. His work integrates field investigations, geochemical modeling, isotope and environmental geochemistry and conceptual hydrogeochemical frameworks to support sustainable groundwater management and environmental protection. He has participated in national and international research projects addressing groundwater contamination, heavy metals, renewable energy–related environmental impacts, and climate-related processes. Prof. Dawood is an active member of professional geological and environmental societies and continues to contribute to scientific advancement through research, teaching, and interdisciplinary collaboration.
