Title
Going Against Gravity -- How do granular materials flow in space?
Speaker
Dr. Olfa D'Angelo (CNRS, University of Toulouse, France)Abstract
Granular materials behave in unexpected ways when gravity is reduced -- but do we understand why? In this presentation, I will discuss how gravity shapes the behavior of granular matter across scales, from industrial powders on Earth to lunar and asteroid regolith. Through low-gravity experiments conducted on multiple platforms, we will unravel how cohesion emerges as a dominant force when gravity weakens, opening new perspectives for both fundamental physics and space exploration.

Short bio:
Olfa D’Angelo is an expert in the physics of granular materials in reduced gravity, working at the interface of soft matter physics and space exploration. She completed her PhD at the German Aerospace Center (DLR) and will join the French National Centre for Scientific Research (CNRS) at the Institut de Mécanique des Fluides de Toulouse (IMFT) in 2027 to establish a research group on Soft Matter in Space.
