Elisabeth Guazzelli (Aix-Marseille University, CNRS, IUSTI, Marseille, France)
4 lectures on: Low-Reynolds-Number Hydrodynamics and Suspension Rheology. Introduction to the dynamics of particulate suspensions. Low-Reynolds number suspensions; microhydrodynamics with single-body and pair-body dynamics. Assemblies of hydrodynamically interacting particles. Suspension rheology

Kirsten Martens (Laboratoire Interdisciplinaire de Physique, CNRS and Grenoble Alpes University, Saint Martin d'Hères, France)
3 lectures on: Mechanics of Glasses. Glasses are created either by a rapid quench in temperature of a liquid or by increasing the packing fraction in a particle suspension above jamming, such that particles are trapped into metastable states within a highly complex potential energy landscape.The dynamics of these systems is strongly out-of-equilibrium and there is no unifying theory to describe the yielding and the flow of these glassy systems under applied forces. However, there exist several approaches, often phenomenological, to tackle these questions and in this course I will cover amongst other things the mode-coupling approach, as well as the microscopic and mesoscopic approaches proposed in the literature.

Bernhard Mehlig (University of Gothenburg, Gothenburg, Sweden)
3 lectures on: Particles in Turbulence Models; preferential concentration, small-scale clustering, relative velocities; effect of Brownian translation/rotation (connection to lecture 1), active particles (connections to lectures 3 and 4); non-spherical particles; open questions.
