Professor Dr.-Ing. Claus Wagner is Honorary Professor for Industrial Aerodynamics, Ilmenau University of Technology, Germany. Since 1998 he has been a Scientist and Head, Section of Numerical Simulations for Technical Flows, of the Institute for Aerodynamics and Flow Technology, German Aerospace Center, G ttingen, Germany. Dr Wagner's research includes experimental investigations on the resonant control of nonlinear dynamic systems, theoretical and numerical investigations of thermal convection in cylindrical containers and Direct Numerical Simulation and Large-Eddy Simulations of turbulent flows in different configurations. He has held numerous visiting positions in Munich as well as in Gainsville, Florida, USA.

After graduating from University Pierre et Marie Curie - Paris 6 in 1995, Professor Pierre Sagaut worked as a research engineer at ONERA (French National Aerospace Research Center) until 2002. That year, he returned to accept a Professorship in Mechanics at the University Pierre et Marie Curie and now teaches there, as well as at the Ecole Polytechnique. He remains a consultant at ONERA, with IFP and CERFACS (France). His primary research interests include fluid mechanics, aeroacoustics, numerical simulation of turbulent flows (both Direct and Large-Eddy Simulation) and numerical methods. He is also involved in uncertainty modeling for CFD. He authored and co-authored more than 90 papers in peer-reviewed international journals and 130 proceeding papers. He is the author of several books dealing with turbulence modeling and simulation. He is a member of several editorial boards: Theoretical and Computational Fluid Dynamics, Journal of Scientific Computing, Progress in CFD. Three times he has received the ONERA award for the best publication, and the John Green Prize (delivered by ICAS, 2002). He is the co-author of Large-Eddy Simulation for Acoustics, also published by Cambridge University Press.
