Flowing matter occurs everywhere around us. There are many examples that illustrate the richness and complexity of flowing matter: from dilute suspensions of active and inactive matter (swimming micro-organisms or inorganic matter transported through the ocean) to dense complex fluids that are suspensions of many interacting parts (glasses, foams).

Flowing matter is now an important research topic with many different facettes. Some have only recently appeared (active matter), while others have recently gained new momentum, due to new experimental techniques such as particle tracking, by recent advances in methods for firstprinciple computer simulations, and guided by new theoretical insights.

These recent developments have brought the fundamental questions of flowing matter into focus. What are appropriate microscopic models? How do microscopic
dynamics and interactions give rise to large-scale macroscopic patterns and dynamics? Which aspects of the dynamics of flowing matter are universal? What role does turbulence play in flowing matter?

In the last few years there has been substantial progress in answering these questions, but there are still fundamental difficulties and many open questions. The aim of this CISM course is to give PhD students, postdocs and young
researchers an overview of current analytical and computational techniques that are used in different fields to describe flowing matter.

The following topics are covered: low-Reynolds-number hydrodynamics; rheology of glasses, foams, and colloidal suspensions; active matter; particles in turbulence. We intend to highlight universal aspects, and the lectures will assess successes and
shortcomings of the state-of the art theory. The goal is to identify key open problems that provide interesting research questions for PhD students, postdocs, and you researchers.

This school is organized in collaboration with the European Cost action MP1305 Flowing matter. In addition to the planned lectures the COST action will arrange a number of shorter research seminars that complement the topics covered in the regular lectures.
