Transport and mixing are among the most important properties of turbulent fluid flows. Indeed, movement of mechanical and thermal energy and material underlies the most basic dynamical phenomena in astrophysics, geophysics and the environment, as well as in biology and myriad industrial and engineering applications. Understanding (i) the fundamental physics underlying the dynamics of these processes and (ii) cutting edge mathematical approaches for their analysis is central to many active research fields. Topics include recent advances in irregular transport and geometric analysis, and developments and novel applications from optimization and control. The primary objective of this workshop is to bring together mathematical scientists working on theoretical and state of the art computational aspects of fluid dynamics focused on quantitative modelling and analysis of turbulent transport and mixing.
