Benayoun Stephane

Holding a PhD and habilitation à diriger les recherches (HDR) in physics of materials from the University of Poitiers, Stephane Benayoun is professeur des universités de classe exceptionnelle in the Sciences et Techniques des Matériaux et des Surfaces (STMS) department at Centrale Lyon.

Director of the Materials of Lyon Doctoral school, he teaches materials science, surface and coating engineering, plasticity, material selection methodologies and processes in mechanical design. After a doctorate dealing with the elaboration of high critical temperature superconducting oxide films by ion beam sputtering, he began his academic career at the Ecole Nationale Supérieure d'Arts et Métiers (ENSAM) in Angers, where he studied the mechanical behavior of surfaces and coatings in relation to surface treatment processes. Since 2005, he has been working at the Laboratoire de Tribologie et Dynamique des Systèmes (LTDS-UMR-CNRS-5513).

In addition to continuing his work at ENSAM, at LTDS he has developed a research focus on surface texturing using ultrafast lasers as well as microinjection of thermoplastics, with a particular interest in wetting behavior, glaciophobic surfaces and adhesion. He has co-authored nearly 80 articles in international scientific journals. He leads scientific research programs (ANR, ...) most often in partnership with industry.

Responsible for the Surface-Friction-Vibration (SFV) research group at LTDS he has also led teaching teams at Centrale Lyon and two masters degrees. Particularly involved in learned societies, he chaired the SF2M Western Section and co-founded its "Indentation" Thematic Group.

Research projects

Stephane Benayoun has been working at the Tribology and Systems Dynamics Laboratory (LTDS-UMR-CNRS-5513) since 2005. At the LTDS, he has developed a research focus on surface engineering, and more specifically on Materials-Properties-Processes relationships. In particular, he has acquired expertise in ultra-short laser surface texturing, PVD deposits as well as microinjection of thermoplastics. He is interested in wetting behavior, glaciophobic surfaces, adhesion and more generally the mechanical behavior of surfaces and coatings integrating biomimetic approaches for the design of functional interfaces. He has co-authored nearly 80 articles in international scientific journals. He leads scientific research programs (ANR, ...) most often in partnership with industry.
