# Fluid structure interactions at (mostly) low Reynolds numbers: Sphere settlings, primary cilia, waves and vortex rings

*By Roberto Camassa, University of North Carolina at Chapel Hill*

The interplay between structures in relative motion with respect to an ambient fluid and density stratifications, including such extreme cases as free surfaces, are a constant source of interesting physical an mathematical phenomena. This talk will outline examples in this area of research involving a combination of analytical, numerical and experimental techniques, stemming from interdisciplinary projects centered around the facilities of the UNC Joint Fluids Lab in collaboration with science departments at UNC.
