Filippo Coletti is Professor of Experimental Fluid Dynamics at ETH Zürich. His research interests are focused along two main axes. On the fundamental side, he studies dispersed multiphase flows, and especially the dynamics of solid particles suspended in turbulent fluids. This includes both the effects of fluid flow on the particle trajectories, and the changes caused by the particles to the fluid flow. These phenomena are especially relevant to environmental processes such as atmospheric precipitation and pollution transport. On the applied side, Coletti investigates bio-fluid mechanics problems. In particular, he explores the relation between anatomical structure and organ-level function in respiratory and cardiovascular settings, by using both idealized and realistic in vitro models. The questions are tackled using a broad range of measurement techniques, including Particle Image Velocimetry and Magnetic Resonance Imaging.
