Research Interests

The main focus of our research are the understanding of self-organization of matter at various scales, from the collective interactions of microscopic particles to geometrically constrained elastic slender objects. These studies, combining simulations, experiments and theoretical models, rely on concepts from out of equilibrium statistical physics, Soft Matter Physics and continuum mechanics.
For example, we try to understand how granular matter flows, the collective self-organization of active particles, the formation of wrinkles or elastic singularities in twisted ribbons, compressed thin sheets.
We also apply our knowledge in elasticity and fluid flow to understand the structure and function of biological organisms.
