Throughout his career, he has focused on the fascinating field of complex fluids. His position as a CNRS Researcher at the Laboratoire Navier, along with postdoctoral experiences at renowned institutions, has given him deep expertise in the mechanics and rheological properties of these materials. His research has made significant contributions to the understanding of phenomena such as shear thickening, shear jamming, cohesion, and aggregate dynamics in granular flows. His work has been published in top-tier scientific journals and has received recognition through awards and media coverage. He has also been actively involved in mentoring Ph.D. students, postdoctoral researchers, and undergraduates, which has helped him develop strong communication and leadership skills.

Its main scientific activity focuses on unsaturated granular materials, in particular their rheological behavior. It aims to understand the mechanical response—both in the solid-type regime and during the flow — of granular materials bound by a non-saturating liquid, which influences the system through viscosity and capillary effects. These materials, which are located between dry granular assemblies and highly concentrated suspensions, are studied both experimentally and by discrete simulations (in collaboration with Jean-Noël Roux and François Chevoir), from their microstructure to their macroscopic behavior.

To develop a complete and experimentally validated model, he designed rheological characterization tests on granular materials with different degrees of saturation, for a given microstructure obtained by controlled deformation and confinement history.
