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.
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).
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.

He has been plenary speaker at the International Congress of Mathematicians ICM2006. He had been responsible of several European research networks. His team has carried out the aerodynamic and hydrodynamic simulations for the optimization of Alinghi, the Swiss sailing yacht that has won two editions of the America's Cup in 2003 and 2007.
Tobias Schneider
Tobias Schneider is an assistant professor in the School of Engineering at EPFL, the Swiss Federal Institute of Technology Lausanne. He received his doctoral degree in theoretical physics in 2007 from the University of Marburg in Germany working on the transition to turbulence in pipe flow. He then joined Harvard University as a postdoctoral fellow. In 2012 Tobias Schneider returned to Europe to establish an independent Max-Planck research group at the Max-Planck Institute for Dynamics and Self-Organization in Goettingen. Since 2014, he is working at EPFL, where he teaches fluid mechanics and heads the 'Emergent Complexity in Physical Systems' laboratory. Tobias Schneider's research is focused on nonlinear mechanics with specific emphasis on spatial turbulent-laminar patterns in fluid flows transitioning to turbulence. His lab combines dynamical systems and pattern-formation theory with large-scale computer simulations. Together with his team, Schneider develops computational tools and continuation methods for studying the bifurcation structure of nonlinear differential equations such as those describing the flow of a fluid. These tools are published as open-source software at channelflow.ch. Publications: Google Scholar
