This workshop is intended to be an exchange forum for scientists working on innovative and efficient techniques for uncertainty quantification and robust design in Fluid Mechanics. More precisely, we hope that this could be source of inspiration for improving and developing new ideas. Three thematic days will be organised around the following themes : (i) Computational methods for uncertainty propagation. (ii) Uncertainty analysis in fluid dynamics simulations. (iii) Sensitivity and Optimization. Each day, three invited lectures are planned in the morning and in the early afternoon. Then, a session with contributed talks (based on abstract selection) will follow.
