I work on the particle-particle interactions in colloidal suspensions and their impact at large scale on their organisation :  self assembly, structuration as a dispersed or condensed phase, or on transport properties rheology, permeability.

Colloidal suspensions and Soft Matter

I developed experimental strategies based on different techniques to understand the link between details of interactions at small scale and macroscopic behavior at large scale including process scale. These strategies are based on instrumentations of different levels of sophistication starting from sedimentation tests to X-ray synchrotron radiation.

Since 2017, I also have access to a in house X-Ray Facility to deveop extensive studies of colloidal organisation in complex systems

Separation and Filtration processes

I also work on engineering aspects related to separation and filtration processes, specifically applied to complex fluids such as slurries, colloidal or aggreates suspensions, gels. The behavior of these systems is so far from granular particles that the design and control of optimal process is frequently counter-intuitive.
