Louay Elsoufi

Associate Professor


Dr. Louay Elsoufi is an Associate Professor of Mechanical Engineering at Beirut Arab University. Previously, he served as an Associate Professor of Mechanical Engineering at Lebanese University, Faculty of Science III and Faculty of Engineering I, and was the Director of the Master’s program in Physics Energetics at Lebanese University, Faculty of Science III. Before that, Dr. Elsoufi was the Chairman of the Mechanical and Energy Engineering Department at Lebanese French University. He also worked as part timer at Lebanese International University and National Conservatory of Arts and Crafts University, and half timer at the University of Technology of Belfort-Montbeliard in France.

Dr. Elsoufi is qualified as an Associate Professor in Mechanical and Civil Engineering by the Ministry of Education and Higher Education in France (Qualification No: 22260370708).

He received his Ph.D. from the University of Technology of Belfort-Montbeliard in 2009, his DEA (Master of Advanced Studies) in Energetics, Materials, and Mechatronics from Lebanese University, Faculty of Engineering, in partnership with the University of Technology of Belfort-Montbeliard in 2003, and his BE in Mechanical Engineering from Lebanese University, Faculty of Engineering, in 2002.

Dr. Elsoufi's current research focuses on Smart Materials and Structures, Green Building with home automation technology, and Thermo-Fluidic Coupling in the presence of acoustic sources.

Dr. Elsoufi also worked as an Engineering Contractor on mechanical installations at DCH hospital in Lebanon.
