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.
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 bachelors level and Fracture mechanics at the masters 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.
Nava Setter
Nava Setter completed MSc in Civil Engineering in the Technion (Israel) and PhD in Solid State Science in Penn. State University (USA) (1980). After post-doctoral work at the Universities of Oxford (UK) and Geneva (Switzerland), she joined an R&D institute in Haifa (Israel) where she became the head of the Electronic Ceramics Lab (1988). She began her affiliation with EPFL in 1989 as the Director of the Ceramics Laboratory, becoming Full Professor of Materials Science and Engineering in 1992. She had been Head of the Materials Department in the past and more recently has served as the Director of the Doctoral School for Materials.
Research at the Ceramics Laboratory, which Nava Setter directs, concerns the science and technology of functional ceramics focusing on piezoelectric and related materials: ferroelectrics, dielectrics, pyroelectrics and also ferromagnetics. The work includes fundamental and applied research and covers the various scales from the atoms to the final devices. Emphasis is given to micro- and nano-fabrication technology with ceramics and coupled theoretical and experimental studies of the functioning of ferroelectrics.
Her own research interests include ferroelectrics and piezoelectrics: in particular the effects of interfaces, finite-size and domain-wall phenomena, as well as structure-property relations and the pursuit of new applications. The leading thread in her work over the years has been the demonstration of how basic or fundamental concepts in materials - particularly ferroelectrics - can be utilized in a new way and/or in new types of devices. She has published over 450 scientific and technical papers.
Nava Setter is a Fellow of the Swiss Academy of Technical Sciences, the Institute of Electrical and Electronic Engineers (IEEE), and the World Academy of Ceramics. Among the awards she received are the Swiss-Korea Research Award, the ISIF outstanding achievement award, and the Ferroelectrics-IEEE recognition award. In 2010 her research was recognized by the European Union by the award of an ERC Advanced Investigator Grant. Recently she received the IEEE-UFFC Achievement Award (2011),the W.R. Buessem Award(2011), the Robert S. Sosman Award Lecture (American Ceramics Society) (2013), and the American Vacuum Society Recognition for Excellence in Leadership (2013).
Luis Guillermo Villanueva Torrijo
Guillermo Villanueva is a Tenure Track Assistant Professor at the Ecole Polytechnique Federale de Lausane (EPFL), Switzerland, in the Mechanical Engineering Institute (IGM). Before joining EPFL he was a Marie Curie post-doctoral scholar at DTU (Denmark) and Caltech (California, US); and before a post-doc at EPFL-LMIS1. He received his M.Sc. in Physics in Zaragoza (Spain) and his PhD from the UAB in Barcelona (Spain).
Since the start of his PhD (2002), Prof. Villanueva has been active in the fields of NEMS/MEMS for sensing, having expertise from the design and fabrication to the characterization and applicability. He has co-authored more than 75 papers in peer-reviewed journals (h-index of 24 WoK, 32 GoS) and more than 100 contributions to international conferences.
He is serving, or has served, on the program committees of IEEE-NEMS, IEEE-Sensors, MNE, IEEE-FCS and Transducers. He is editor of Microelectronic Engineering. He has co-organized MNE2014 and SNC2015; and he is currently co-organizing the short courses at Transducers 2019 and the 16th International Workshop on Nanomechanical Sensors (NMC2019).
