I am an associate professor in the Department of Mathematics at the University of New Valley, Al-Kharga, Al-Wadi Al-Gadid, Egypt and in the Department of Mathematics at Northern Border University, Arar, Northern Borders, KSA. My research focuses on effect of nanoparticle, heat, and mass transfer in fluid mechanics via porous media. I am studying the following topics: nanofluids; non-Newtonian fluids, chemical reactions effect, numerical treatments of nanofluids flow, porous media, magnetic field. I have more than 150 scientific published papers in highly impact journals. For the third year in a row, I have been ranked in the top 2% of the world's most cited scientists for research conducted by Stanford University in collaboration with Elsevier Publishing and Scopus in Mechanical Engineering and Transport field.
