Nadhir Lebaal received his Ph.D. in Mechanics and Energy from the Institute National Polytechnique de Lorraine (INPL), France. He was an Assistant Professor in computational mechanics at the High School of Engineering Design (GIP-InSIC) in Saint Dié des Vosges (France) for two years and an Associate Professor at the Ecole des Mines of Albi-Carmaux for one year. He joined the University of Technology of Belfort-Montbeliard (France) in 2009 as a permanent full-time Associate Professor. He currently conducts research in the ICB-COMM/UMR CNRS 6303 laboratory. His research interests include numerical modeling, optimization, and material processing and design. He is the head of Engineers Formation by Apprenticeship (FISA-CoMET) and manages a research axis in the area of robust engineering and optimization of product–process–material interactions. His major research interests are polymer processing design, the development of mathematical optimization applied to extrusion design, sheet metal forming, and, recently, additive manufacturing.
