Prof. François Avellan, director of the EPFL Laboratory for Hydraulic Machines, graduated in Hydraulic Engineering from Ecole nationale supérieure d'hydraulique, Institut national polytechnique de Grenoble, France, in 1977 and, in 1980, got his doctoral degree in engineering from University of Aix-Marseille II, France. Research associate at EPFL in 1980, he is director of the EPFL Laboratory for Hydraulic Machines since 1994 and, in 2003, was appointed Ordinary Professor in Hydraulic Machinery. Supervising 37 EPFL doctoral theses, he was distinguished by SHF, Société hydrotechnique de France, awarding him the "Grand Prix 2010 de l'hydrotechnique". His main research domains of interests are hydrodynamics of turbine, pump and pump-turbines including cavitation, hydro-acoustics, design, performance and operation assessments of hydraulic machines. Prof. Avellan was Chairman of the IAHR Section on Hydraulic Machinery and Systems from 2002 to 2012. He has conducted successfully several Swiss and international collaborative research projects, involving key hydropower operators and suppliers, such as:
- Coordination for the FP7 European project n° 608532 "HYPERBOLE: HYdropower plants PERformance and flexiBle Operation towards Lean integration of new renewable Energies" (2013-2017);
- Deputy Head of the Swiss Competence Center for Energy Research – Supply of Electricity (SCCER-SoE) to carry out innovative and sustainable research in the areas of geo-energy and hydropower for phase I (2013-2016) and Phase II (2017, 2010) to be approved.

Mohamed Farhat
M. Farhat was born in Casablanca in 1962 (Moroccan citizen). He graduated at Ecole Nationale Supérieure d'Hydraulique et de Mécanique de Grenoble (France. He joined The LMH laboratory in 1986 as research assistant. He completed in 1994 a Ph.D. thesis on Cavitation. He joined the R&D department of Hydro-Quebec in Montréal (Canada) in 1995 where he was in charge of several research projects in the areas of production and transportation of hydropower and mainly the monitoring of large hydro turbines. Since 2001, he is senior scientist at the LMH laboratory, head of the cavitation group. He is also lecturer in Master and Doctoral programs. He is member of the Doctoral Committee in Mechanics.
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.
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).
Peter Monkewitz
After graduating in physics from the Swiss Federal Institute of Technology in Zurich, he received his Ph.D. from the same institution in 1977 with a thesis on internal acoustics. From 1977-80 he was a research associate in the Aerospace Department of the Univ. of Southern California in Los Angeles, where he worked experimentally and theoretically on jet noise and hydrodynamic instabilities. In 1980 he joined the faculty of the School of Engineering at UCLA where he made research contributions in several areas. In the field of hydrodynamic instability he had a hand in the popularization of the concept of absolute instability in fluid mechanics, the development of the concept as well as of the asymptotic analytical description of global modes in nonparallel flows, and in the modelling of vortex shedding from bluff bodies. Other areas of research include internal acoustics, jet mixing, in particular in low-density jets in which he co-discovered enhanced mixing by "side-jets," flow control, transition to turbulence, turbulence and, most recently, flame instabilities. In 1988 he was awarded the Humboldt prize and spent the academic year 1989/90 as Humboldt awardee at the Technical University in Berlin. In 1992 he was elected Fellow of the American Physical Society. Since 1993 he holds the chair for experimental fluid mechanics and heads the Laboratory of Fluid Mechanics (LMF) of the Swiss Federal Institute of Technology in Lausanne (EPFL), Switzerland. He has been Chairman of its Mechanical Engineering Department from July 1997 to December 2000, co-organizer of the 1999 Research programme on turbulence at the Isaac Newton Institute in Cambridge, UK, Associate Editor of the Journal of Fluid Mechanics from 1995 to 2000 and a member of the EUROMECH Council. He is currently an Associate Editor of Physics of Fluids , a member of the IUTAM general assembly, a member of the schoolwide EPFL Academic Promotions Committee and part-time "program monitor" for the Swiss National Science Foundation (member of its Research Council).
