Mr. Abdalla El Ayyat | Earth and Planetary Sciences | Best Researcher Award
Assiut University Egypt
Prof. Dr. Abdalla Mousa Tolba Ibrahim El Ayyat is an eminent Egyptian geologist and Professor of Sedimentary Rocks and Stratigraphy at the Geology Department, Faculty of Science, Assiut University, Egypt. Born on July 18, 1961, in El Minia, Egypt, he has devoted his career to the detailed study of sedimentary basins, stratigraphic sequences, and carbonate formations, especially in Egyptβs desert and Nile Valley regions. With over four decades in academia and research, Prof. El Ayyat is known for his deep commitment to geological education, stratigraphic frameworks, and regional paleoenvironmental reconstruction.
Profile
π Education
Prof. El Ayyat began his academic journey with a B.Sc. in Special Geology (Distinction) from Assiut University in 1983. He earned his M.Sc. in Sedimentology and Stratigraphy in 1989, focusing on Lower Eocene carbonates in Upper Egypt. He completed his Ph.D. in 1998, where he studied the stratigraphic and sedimentological evolution of the Eocene sequence between Minia and Beni Suef. His academic training has laid a strong foundation for a prolific career in stratigraphy and sedimentary research.
π§ͺ Professional Experience
Starting as a demonstrator in 1983, Prof. El Ayyat progressed through roles of assistant lecturer, guest researcher, and lecturer at Assiut University and abroad. He gained international exposure at the Technical University of Munich (Germany) and Vienna University (Austria) through prestigious scholarships. He was promoted to Professor in 2017 and later served as Head of the Geology Department from 2019 to 2021. Since 2021, he holds the title of Emeritus Professor, continuing to inspire students and researchers through mentorship and academic leadership.
π¬ Research Interests
Prof. El Ayyatβs research interests center around sedimentology, stratigraphy, and basin analysis, particularly of Cretaceous and Eocene formations in Egypt. He has contributed significantly to understanding depositional environments, diagenetic processes, and the paleoecological significance of fossil assemblages. His work integrates lithostratigraphy, biostratigraphy, facies analysis, and clay mineralogy to reconstruct geologic history and sea-level fluctuations in North Africa.
π Awards & Recognitions
Prof. El Ayyat has been recognized by academic institutions and scientific conferences for his outstanding contributions to geology, including international collaborations and conference presentations. His leadership roles and research scholarships in Austria and Germany further highlight his international stature. He has also played key roles in organizing and participating in regional and international geology conferences, fostering knowledge exchange in Earth Sciences.
