Biographie
Gregory ABADIAS is Professor at the Physics Department of the University of Poitiers, France. He received his Ph.D. in Materials Science in 1998 at National Polytechnic Institute of Grenoble (INPG), and he is currently group leader of thin films activities at CNRS Pprime Institute in Poitiers. He conducts research on a range of topics related to nanoscale thin films, including mechanical, electrical and optical properties of metallic, nitride or oxide systems, as well as hard and protective coatings in the form of nanocomposites or multilayers. His current research interests focus on the understanding of thin film growth dynamics using real-time and in situ diagnostics, and multi-scale modelling with main emphasis on the stress development during sputter-deposition of polycrystalline and epitaxial layers. He is co-authors of more than 150 papers in peer-review journals and one book chapter. He is member-elected to the Scientific Council of the Physics Institute of CNRS since 2019, as well as French representative of the Surface Engineering Division of IUVSTA for 2019-2022 triennium. He has been involved in the organization of several symposia or workshops at international conferences (ICMCTF, EMRS) and serves as Editor of Surface and Coatings Technology journal since 2016
