As my research experiences become more diversified, I found myself extremely interested in the investigation of small scales biological phenomena by the design of simple physical experimental systems. This approach has the double benefit of:
As my research experiences become more diversified, I found myself extremely interested in the investigation of small scales biological phenomena by the design of simple physical experimental systems. This approach has the double benefit of:
- Creating fundamental knowledge applicable in biology and physics;
- Developing bio-inspired system with stunning properties.

We aim to understand the mechanisms of mucus clearance in the airways from a hydrodynamic perspective. We combine numerical modeling and laboratory experiments to study the conditions that promote effective mucus clearance.

With Corentin Trégouët and Mathilde Lepoitevin
The project, in collaboration with the Institute of Porous Materials in Paris (ENS-ESPCI-CNRS), and the CBI of ESPCI Paris, aims to control diffusion-osmosis at chemical interfaces for controlled passive mixing near the surface of ion-exchange membranes. This will inhibit concentration polarization and unlock the full potential of blue energy technologies.

How the beating of cellular cilia in a surrounding fluid gives rise to fluid transport and coordinated cilia motions is a 70-year-old problem, but it remains an open question due to the complexity and the diversity in the length scale of the phenomenon involved. Theoretical studies suggest that the non-Newtonian hydrodynamic coupling between cilia plays a crucial role. This conjecture requires a systematic study of the non-Newtonian effects on large arrays of passive slender objects. Yet, no such experimental investigation has been conducted because of the technological difficulty of making well controlled large arrays of micron-size structures with high aspect ratios, in an environment suitable to resist highly viscous and viscoelastic flows. We conduct the first systematic, quantitative study of the interaction of a large array of micrometric passive cilia-like structure with a biomimetic biopolymer solution with non-Newtonian features.

PhD in the Gulliver laboratory, ESPCI Paris, PSL university. Doctoral contract with the École Doctorale Physique en Île-de-France.
Water droplets swimming in oil are a very peculiar example of micro-swimmers. Being a potential biocompatible carrier at the microfluidic scale, it is of utmost interest to understand their swimming :
in confined geometries - from one wall to 1D microchannels,
against an external pertubation - like a force, or an external flow,
when they are interacting with each other, from binary collisions to collective motion.
