Biography

Dr. Emad Ashmawy is currently working as Associate Professor of Mathematics in the Faculty of Science at Beirut Arab University. He has received his PhD in Mathematics from Alexandria University in 2007 where he worked as assistant lecturer at the department of Mathematics and Computer Science in the Faculty of Science at Alexandria University. His research interests are in the fields of Applied Mathematics and Fluid Dynamics, which are devoted to the study of the mass, momentum and energy conservation laws describing the motion of different types of fluids (e.g. viscous, microstretch, micropolar, viscoelastic and couple stress fluids) subject to prescribed boundary conditions. He has more than 20 publications in this field.
