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.
Brice Tanguy Alphonse Lecampion
I am currently an assistant Professor and the head of the Geo-Energy Lab - Gaznat Chair on GeoEnergy at Ecole Polytechnique Fédérale de Lausanne (EPFL), Switzerland. Prior to joining EPFL, I have worked for Schlumberger in research and development from 2006 until May 2015 - serving in a variety of roles ranging from project manager to principal scientist in both Europe and the United States. I received my PhD in mechanics from Ecole Polytechnique, France in 2002 and worked as a research scientist in the hydraulic fracturing research group of CSIRO division of Petroleum resources (Melbourne, Australia) from 2003 to 2006. During my time in Schlumberger R&D, I have worked on problems related to the integrity of deep wells, large scale monitoring of reservoir deformation and more specifically on the stimulation of oil and gas wells by hydraulic fracturing. My current research interests cover hydraulic fracture mechanics, mechanics of porous media and dense suspensions flow.

Michel Deville
Michel Deville est né le 26 février 1945 à Charleroi (Belgique). Ingénieur civil électricien-mécanicien de l'Université Catholique de Louvain (1968), il y a présenté sa thèse de doctorat en sciences appliquées en 1974. Le sujet en était l'intégration numérique des équations de Navier-Stokes par la méthode des différences finies.
En 1974-1975, il séjourne en tant que boursier OTAN au Département de mathématiques du MIT chez le Prof. S.A. Orszag. A cette occasion, il se familiarise avec les méthodes spectrales pour le calcul des écoulements de fluides incompressibles. Ensuite, sa carrière académique se déroule à l'Université de Louvain: chargé de cours, professeur, professeur ordinaire.
Depuis 1979, il est collaborateur à la division d'aérodynamique de l'ONERA (Chatillon, France). Il est spécialiste des méthodes spectrales. Il applique les méthodes numériques à la simulation directe d'écoulement des fluides, à la modélisation de la turbulence et au calcul des fluides non-Newtoniens. Il est nommé professeur à l'EPFL le 1er septembre 1993, où il conduit les travaux liés à la mécanique des fluides numériques.Il prend sa retraite le 28 février 2010. Il est actuellement rédacteur en chef de la revue Computers and Fluids.

Christophe Ancey
Christophe Ancey has both a PhD and an engineering degree granted by the Ecole Centrale de Paris and the Grenoble National Polytechnic Institute. Trained as a hydraulics engineer, he did his doctoral work under the supervision of Pierre Evesque from 1994 to 1997 on rheology of granular flows in simple shearing. He was recruited in 1998 as a researcher in rheology at the Cemagref as part of the Erosion Protection team directed by Jean-Pierre Feuvrier, which has since become the laboratoire "Storm Erosion, Snow and Avalanche Laboratory". Parallel to this research activity, with Claude Charlier He set up a consulting firm for engineering contracting called Toraval (www.toraval.fr), which has become the major player in the avalanche field in France. Since 2004, He is a fluid-mechanics professor at EPFL and he is the director of the Environmental Hydraulics Laboratory.
He is associate editor of Water Resources Research, one of the leading journal in the field.
