Michel Rappaz
Après un doctorat en physique du solide (1978) de l’Ecole Polytechnique Fédérale de Lausanne (EPFL), un post-doc à Oak Ridge National Laboratory, Michel Rappaz rejoint l’Institut des matériaux de l’EPFL en 1981. Après un passage de deux ans dans un bureau d’ingénieurs, il revient à l’EPFL en 1984 où il est nommé Professeur titulaire en 1990, puis Professeur ordinaire en 2003. Après sa retraite de l’EPFL en 2015, il est actuellement Professeur émérite et consultant indépendant auprès de divers centres de recherche et industries. Ses principaux centres d’intérêt sont les transformations de phase et la solidification, en particulier le couplage des aspects macroscopiques de transferts de chaleur et de masse à l’échelle des procédés avec les aspects microscopiques de germination-croissance des microstructures et des défauts. Parmi ses diverses réalisations, on peut mentionner le développement d’Automates Cellulaires couplés avec la méthode d’Eléments Finis (modèle CAFE) pour la prédiction des structures de grains en solidification, le développement de modèles granulaires pour la fissuration à chaud, l’application de la méthode de champ de phase pour la compréhension de diverses microstructures, la découverte de la germination assistée dans certains alliages par des phases quasicrystallines, ainsi que de nombreuses études touchant aussi bien les aspects fondamentaux de formation des structures que des aspects plus appliqués des procédés. Certains modèles développés dans son laboratoire ont été commercialisés par une spin-off fondée en 1991 (Calcom SA), faisant partie actuellement du groupe français ESI. Michel Rappaz a initié en 1992 un cours annuel de formation continue en solidification, suivi à ce jour par plus de 900 participants venant d’une quarantaine de pays. Il collabore actuellement avec une autre spin-off du laboratoire fondée en 2014, Novamet SàrL. Michel Rappaz a reçu de nombreux prix et distinctions, en particulier le prix Mathewson de co-auteur (1994) et auteur (1997) de l’American Mineral, Metals and Materials Society (TMS), le prix de la fondation Koerber avec les Profs Y. Bréchet et M. Asbby (1996), la médaille Sainte-Claire Deville (1996) et la Grande Médaille (2011) de la Société Française des Matériaux (SF2M), le prix Bruce Chalmers de la TMS (2002), le prix Mc Donald Memorial Lecture du Canada (2005), la médaille d’or de la Société Européenne des Matériaux (FEMS, 2013) et le prix Brimacombe de la TMS (2015). Il fait partie des “Highly-Cited Authors” de ISI, il est fellow des sociétés ASM, IOP et TMS, et a écrit plus de 200 publications et deux livres.
Andreas Mortensen
Andreas Mortensen is currently Professor and Director of the Institute of Materials at the Swiss Federal Institute of Technology in Lausanne (EPFL), where he heads the Laboratory for Mechanical Metallurgy. He joined the faculty of EPFL 1997 after ten years, from 1986 to 1996, as a member of the faculty of the Department of Materials Science and Engineering at the Massachusetts Institute of Technology, where he held the successive titles of ALCOA Assistant Professor, Associate Professor, and Professor.  His research is focussed on the processing, microstructural development and mechanical behavior of advanced metallic materials with particular focus on metal matrix composites and metal foams, on infiltration processing and capillarity, and on damage and fracture in metallic materials. He is author or co-author of two monographs, around one hundred and eighty scientific or technical publications and twelve patents.  Born in San Francisco in 1957, of dual (Danish and US) nationality, Andreas Mortensen graduated in 1980 from the Ecole Nationale Supérieure des Mines de Paris with a Diplôme d’Ingénieur Civil, and earned his Ph.D. in the Department of Materials Science and Engineering at MIT in 1986. Besides his academic employment, he was a postdoctoral researcher at Nippon Steel during part of 1986, and was invited professor at the Ecole des Mines in Paris during the academic year 1995 to 1996. He is a member of the editorial committee of International Materials Reviews and has co-edited four books. He is a Fellow of ASM, a recipient of the Howe Medal and the Grossman Award of the American Society of Metals, was awarded the Péchiney Prize by the French Academy of Sciences and the Res Metallica Chair from the Katholieke Universiteit Leuven, received three EPFL teaching awards, is one of ISI’s Highly Cited authors for Materials Science since 2002 and was awarded an ERC advanced grant in 2012.
John Botsis
John (Ioannis) Botsis obtained his diplôme in civil engineering at the University of Patras, Greece in 1979. He continued his education at Case Institute of Technology in Cleveland Ohio/USA, where he received his MS and Ph.D. in 1984. After two years at the research center for national defense in Athens he was nominated assistant professor at the University of Illinois in Chicago, associate in 1991 and full professor in 1995. In 1996, he was nominated professor of solids and structural mechanics at the EPFL.  At EPFL he teaches ‘mechanics of structures’ and ‘mechanics of continuous media´ at the bachelor’s level and ‘Fracture mechanics’ at the master’s and doctoral levels. His research covers the mechanics of solids and structures, fracture mechanics and micromechanics of polymers, metals and their composites as well as biomechanics. He is also actively involved in full-filed optical methods for surface strain measurements as well as internal strain measurements using fiber Bragg grating sensors, aimed at characterizing micromechanics of fracture, residual strains and strain distribution in composite laminates for structural monitoring. Funding for his research comes from the Swiss National Science Foundation, State Secretariat for Education and Research and Swiss industry. He retired on February 28, 2020.
