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 dIngénieur 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 ISIs Highly Cited authors for Materials Science since 2002 and was awarded an ERC advanced grant in 2012.
Lukas Kühn
Lukas Kühn graduated in biochemistry at the Swiss Federal Institute of Technology in Zürich. He received his PhD in 1979 for a thesis with Jean-Pierre Kraehenbuhl at the University of Lausanne. After postdoctoral work in Lausanne and with Frank Ruddle at Yale University, USA, he became group leader at ISREC in 1984, was promoted senior scientist in 1988 and EPFL Adjunct Professor (professeur titulaire) in June 2008.
César Pulgarin
Prof. C. Pulgarin is Chemist from Lausanne University, Master in environmental chemistry from Geneva University, Ph D in synthesis bio-inspired of natural substances from Neuchâtel University. During his education he carried out several industrial trainings.
Since March 1989, he has been working at the EPFL where he is leader of the Advanced Oxidation Processes Group (GPAO) active in the development chemical, photochemical, electrochemical, ultrasonic processes, their coupling between them and with biological systems to degrade chemical and microbiological pollutants in water and air. He has an H index of 40 and he is the world most cited author in 1) TiO2 photo-assisted bacterial inactivation in water and 2) Coupling of photochemical and biological processes for pollutant degradation. He has been involved in ten African, South American and European international research projects. He has been Swiss representative in COST program 540.
Karen Scrivener
De nationalité anglaise, Karen Scrivener est née en 1958. Au cours de sa carrière, ses travaux et sa recherche traitaient des domaines suivants: Identification du développement microstucturale pendant l'hydratation du ciment. Elaboration d'une approche multitechnique pour étudier la microstucture des ciments et bétons, avec accent sur la quantification par analyse des images d'électrons retrodiffusés. Caractérisation de l'auréole de transition de la pâte de ciment autour des granulats. Compréhension des processus de dégardation des bétons, en particulier le gonflement lié à la formation de l'éttringite retardée dans les bétons étuvés.
Emmanuel Denarié
Emmanuel Denarié is a civil engineer, with a PhD in Materials Science. He worked for 3 years in a civil engineering company where he was in charge of the design of structures and the maintenance of bridges. He has 30 years’ experience on research and applications in the field of building materials, advanced concretes, and rehabilitation of reinforced concrete structures. He is since 2000 senior scientist and lecturer in the Laboratory for Maintenance and Safety of structures, at Ecole Polytechnique Fédérale de Lausanne (EPFL), in charge of research and development activities on the application of concretes and advanced cementitious materials to the improvement of existing and new structures. In 2013, under the lead of Emmanuel Denarié, in cooperation with CEREMA, Subdivision des Phares et Balises from Lorient, and Lafarge, a turret at sea (Le Cabon, Brittany, France) was reinforced by a cast on site 60 mm thick UHPFRC shell. The strain hardening mix was developed jointly with Lafarge. This successful application in extreme conditions of access and restraint of the substrate (thin ring geometry) opened the way to large-scale industrial applications of UHPFRC for the reinforcement of existing structures.
Xile Hu
Xile Hu was born in 1978 in Putian, southeastern China. He entered the Peking University in Beijing in 1996. Besides learning too little chemistry, his biggest regret in the college was not able to correct his southern accent in Mandarin. After graduated from PKU, he went to the United States and began his doctoral studies at the University of California, San Diego. In December 2004, he finished with a Ph.D. in chemistry and some fond memories of the beautiful city of San Diego. He then moved to the Los Angeles area and become a postdoctoral scholar at the California Institute of Technology. There he enjoyed numerous stimulating scientific (and other) discussions with friends and colleagues. He also made plenty of friends outside the campus and was a frequent in many local Chinese restaurants. In 2007, after two pleasant visits to Switzerland, he decided to move across the continent one more time and join the faculty of the École Polytechnique Fédérale de Lausanne (EPFL). He now directs the Laboratory of Inorganic Synthesis and Catalysis and is interested in developing chemistry for synthesis, energy and sustainability.

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.
