C. Tropea: Professor Tropea studied and worked in Toronto, Karlsruhe and Erlangen before taking the Chair of Fluid Mechanics and Aerodynamics at the Technical University of Darmstadt in 1997. His background is in experimental fluid mechanics and he has authored numerous book sections and journal publications on this subject. He is currently Editor of Experiments in Fluids from Springer-Verlag and was previously Editor-in-Chief of Measurement Science and Technology from IOP Publishing. J. F. Foss  Professor Foss received his BSME (1961), MSME (1962) and Ph.D. (1965) from Purdue University. He has been on the faculty at Michigan State University since 9/1964. He served as the NSF Program Director for Fluid Dynamics and Hydraulics (1998-2000). His research specialty is vorticity measurements. His research group addresses fundamental and applied problems in turbulent flows. The latter are primarily associated with automotive applications. He is a Fellow of ASMEand the A.V. Humboldt Stiftung and a Chartered Physicist of the IOP. He holds 7 patents involving fluid mechanics. A. Yarin: Alexander Yarin is currently a Professor at the Department of Mechanical and Industrial Engineering at the University of Illinois at Chicago, USA. In 1990-2005 he was a Professor at the Faculty of Mechanical Engineering at the Technion-Israel Institute of Technology. Professor Yarin is an applied physicist working in the field of fluid mechanics. He received his PhD and Habilitation degrees from the Institute for Problems in Mechanics, USSR Academy of Sciences, Moscow. His main contributions are related to the free surface flows (jets, films, fibers, threads and droplets) of Newtonian and rheologically complex liquids. He is an author of 2 monographs, 5 chapters in books and 170 research articles.
