Accurate characterization of the changes made to surface properties thanks to surface analysis methodologies which are developed to understand the mechanisms involved in various high technology functionalization / coatings intended for future industrial applications.
Biography
Didier LEONARD is Professor at the Université Claude Bernard Lyon 1 since 2003 (Professeur 2ème classe in 2003; Professeur 1ère Classe in 2008 and Professeur Classe Exceptionnelle Echelon 1 in 2019). Engineer in Materials Sciences from Université Catholique de Louvain (Louvain-la-Neuve, Belgium), he got his Ph.D. degree in the same University in 1996. He was then successively appointed as Post-doc at the department of materials science of the Federal Institute of Technology in Lausanne (EPFL, Lausanne, Switzerland) (1996-2000) and as Surface analysis scientist at the Analytical Technology Department of General Electric Plastics Europe (Bergen op Zoom, The Netherlands) (2000-2003). In 2003, he became Professor at the Université Claude Bernard Lyon 1 within the Laboratoire des Sciences Analytiques (now ISA – Institut des Sciences Analytiques UMR 5280 since 2011) where he has been leading a research team bringing together specialists of surface science and sensor developments. He was the (co-)leader of the then newly formed SIMS team and was the coordinator of the Surfaces, (bio)Interfaces & Micro/nano Systems (SIMS) research axis of ISA, being also leader of one of the three SIMS research groups (Surfaces group). He was also an elected member of the ISA Council (Conseil d’Unité). He is currently still leading the Surfaces group within the SMART research axis at ISA.
For what concerns his teaching activities, Didier LEONARD is a Lecturer at Polytech Lyon (Engineer School of the Université Claude Bernard Lyon 1) in the Materials and Surface Engineering (Matériaux et Ingénierie des Surfaces) department. He also serves as Director for International Relations at Polytech Lyon and is member of Polytech Lyon executive committee (Comité de Direction). Didier LEONARD is also teaching in 8 masters from Université Claude Bernard Lyon 1.
For what concerns his scientific activities, Didier LEONARD has developed a strong experience in applying adequate surface characterization to understand the mechanisms of surface modification processes (functionalization, coatings) to trigger specific surface driven properties. Over the years, he has been working on high variety of material substrates (polymers, textiles, papers, semi-conductors, metals,…) through numerous collaborative projects (ANR, FUI, ISI, EU, industrial collaborations,…) and working on applications as diverse as plasma surface treatments applied to polymers, surface modification of textiles, sensor development, photoactivatable grafting, antimicrobial or photocatalytic coatings, release of additives from packaging, tribochemistry characterization,…. He is currently co-author of over 110 publications (h-index = 22), 1 patent, 12 chapter books and over 110 communications (oral/poster) in international conferences (including 16 invited talks). He is member of several evaluation committees including ANR and the Techtera Comité Scientifique et Technique.
