François Gallaire
Né le 26 février 1975, François Gallaire obtient, en 1998, le diplôme dingénieur de lEcole Polytechnique à Paris et, en 1999, un master en « Physique des liquides » à lUniversité Pierre et Marie Curie, toujours à Paris. Il rejoint ensuite le Laboratoire dhydrodynamique (LadHyX) à lEcole polytechnique où il soutient, en 2003, une thèse sur le thème des instabilités des jets tournants et sur le contrôle de léclatement tourbillonnaire sous la direction de Jean-Marrc Chomaz. En 2003, il est nommé chargé de recherche au CNRS au Laboratoire J.A. Dieudonné de lUniversité de Nice Sophia-Antipolis.En 2009, il rejoint l'EPFL pour y fonder le laboratoire des mécanique des fluides et instabilités (LFMI). Ses recherches se concentrent sur létude des propriétés fondamentales de stabilité des écoulements de fluides et sont guidées par les applications réelles, en particulier le contrôle des écoulements. Récemment, il a réalisé dimportantes contributions dans les domaines de la micro-fluidique (lanalyse de la manipulation par laser dune goutte dans un micro-canal) et la dynamique des bio-fluides (le descriptif mécanique de lanévrisme de laorte abdominale).
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.
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.
