Philippe Buffat
Born in Lausanne (Switzerland) in 1942. EPUL physics engineer diploma in 1967 and EPFL PhD in physics in 1976. From 1966 he studies at the Experimental Physics Laboratory (Prof. J.P. Borel) the physical properties peculiar to the very small size metal crystals and gets a PhD degree for his thesis "Abaissement de la température de fusion de petits cristaux d'or par effet de taille thermodynamique" (Lowering of the melting temperature of small gold crystals by thermodynamic size effect). In 1971, he starts to develop an electron microscopy facility available to all EPFL students and researchers (nowadays Centre Interdisciplinaire de Microscopie Electronique CIME) that he manages till 2007. In parallel he teaches the principles of electron microscopy and the Experimental methods of physics at the Physics/Basic Sciences School (SB). In addition, he trains a large part of the facility users. Honorary professor BS/EPFL he carries-out a free-lance research at CIME and in collaboration with the Institute of Crystallography of the Russian Academy of Sciences (ICRAS, Moscow) and the International Centre of Electron Microscopy for Material Science (IC-EM AGH Krakow) This activity covers all the techniques related to transmission and scanning electron microscopy applied to materials science and solid-state physics. His interest is directed towards the structure of nanocrystals, their size effects and behavior under strong electron irradiation, the phase transitions in perovskites, the characterization of nanophases, multilayer and interface structures of crystalline materials and bioceramics. More recently a large research part has moved to understanding/pointing-out the adequacy between the limits of the instruments and their interpretation means in regard of their use in a multiusers facility with a large turnover and a wide range of materials/structures. He is past-president (2006-2007) of the Société Française des Microscopies (Sfµ), honorary member of the Sfµ and of the Swiss Society of Optics and Microscopy (SSOM).
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.
Jean-François Molinari
Professor J.F. Molinari is the director of the Computational Solid Mechanics Laboratory (http://lsms.epfl.ch) at EPFL, Switzerland. He holds an appointment in the Civil Engineering institute, which he directed from 2013 to 2017, and a joint appointment in the Materials Science institute. He started his tenure at EPFL in 2007, and was promoted to Full Professor in 2012. He is currently an elected member of the Research Council of the Swiss National Science Foundation in Division 2 (Mathematics, Natural and Engineering Sciences), and co editor in chief of the journal Mechanics of Materials. J.F. Molinari graduated from Caltech, USA, in 2001, with a M.S. and Ph.D. in Aeronautics. He held professorships in several countries besides Switzerland, including the United States with a position in Mechanical Engineering at the Johns Hopkins University (2000-2006), and France at Ecole Normale Supérieure Cachan in Mechanics (2005-2007), as well as a Teaching Associate position at the Ecole Polytechnique de Paris (2006-2009). The work conducted by Prof. Molinari and his collaborators takes place at the frontier between traditional disciplines and covers several length scales from atomistic to macroscopic scales. Over the years, Professor Molinari and his group have been developing novel multiscale approaches for a seamless coupling across scales. The activities of the laboratory span the domains of damage mechanics of materials and structures, nano- and microstructural mechanical properties, and tribology.
