Mohamed Gad-el-Hak

{

Mohamed Gad-el-Hak is a biomechanical engineer, currently the Inez Caudill Eminent Professor of biomedical engineering and professor of mechanical engineering at Virginia Commonwealth University in Richmond, VA.

Mohamed Gad-el-Hak was born in Tanta, Egypt, but grew up in Cairo. He received his B.Sc. (summa cum laude) in mechanical engineering from Ain Shams University in 1966 and his Ph.D. in fluid mechanics from the Johns Hopkins University in 1973, under Stanley Corrsin. Gad-el-Hak lived in the United States of America since 1968, and became a U.S. citizen in 1981.

Gad-el-Hak was senior research scientist and program manager at Flow Research Company in Seattle, Washington, and then professor of aerospace and mechanical Engineering at the University of Notre Dame, finally coming to Virginia Commonwealth University in 2002 as chair of mechanical engineering, later mechanical and nuclear engineering. He has also worked at the University of Southern California, University of Virginia, Institut National Polytechnique de Grenoble, Université de Poitiers, Friedrich-Alexander-Universität Erlangen-Nürnberg, Technische Universität München, and Technische Universität Berlin.

Gad-el-Hak is known for developing novel diagnostic tools for turbulent flows, including the laser-induced fluorescence (LIF) technique for flow visualization; for discovering the efficient mechanism via which a turbulent region rapidly grows by destabilizing a surrounding laminar flow. He has conducted the seminal experiments that detailed the fluid–compliant surface interactions in turbulent boundary layers; introduced the concept of targeted control to achieve drag reduction, lift enhancement, and mixing augmentation in wall-bounded flows; developed a novel viscous pump suited for microelectromechanical systems (MEMS) applications. His work on Reynolds number effects in turbulent boundary layers, published in 1994, marked a paradigm shift in the subject. His 1999 paper on the fluid mechanics of microdevices established the fledgling field on firm physical grounds and is one of the most cited articles of the 1990s.
