Biography

Prof. Dr Mohamed Gomaa, head of geophysical exploration research Group, Central Laboratories Network and Center of Excellence, National Research Centre (NRC). He was born in 1966, Cairo, Egypt. He received his MSc. and PhD degrees in geophysics from the Cairo University, Egypt in 1996 and 2004, respectively. He became a professor of geophysics at the National Research Centre (NRC). His major research interests involve modeling and simulation of electrical properties of rocks and minerals with a focus on physics properties of texture between grains, mixture laws, composites and mixtures. His outstanding scientific career was awarded the Egyptian State Incentive Award (Egypt) in Geological Sciences from the Ministry of Higher Education and Scientific Research (2010). In 2013 he was awarded the scientific excellence award from the NRC, Egypt. In 2014 he was awarded the appreciation award (NRC) for members with high h-index point’s outputs. In 2016 he was earned the National Research Centre award of appreciation at the occasion of 60 years of the presence of the NRC. He has an Egyptian patent entitled "Pb-free transparent dielectric layer for the plasma display panel, No. 28233". He teaches four courses of Geophysics and geology at Faculty of Science (Helwan University), and at Faculty of Girls (Ain-Shams University). He has a chapter in Horizons published by Earth Science Research. He is the author of more than 36 papers published in international journals and submitted more than 20 abstracts in international workshops and conferences with different topics: applied geophysics, geophysics, geology. He acts regularly as an editor, associate editor, desktop reviewer and reviewer for many (200) leading international scientific journals and scientific papers. In 2004, he shared in establishing and founding the Egyptian Society of Applied Petrophysics (ESAP) and the Central Internet Unit (NRC). He is one of the organizing board and technical committee of nine international conferences. Formal Secretary of the geological branch at Egyptian syndicate of scientific professions (8/2019). Member of the National Committee for "Earth Physics" from the Academy of Scientific Research and Technology.
