Je dirige actuellement l'UMR Gulliver 7083, Unité de recherche implantée à l'ESPCI.

Mes activités de recherche concernent la physique de la "matière molle". Je m'intéresse en particulier aux comportements des polymères aux interfaces,  à la dynamique du mouillage et aux ondes de capillarité-gravité.
Pour mes activités d'enseignement à l'ESPCI, voir ici .

I am Director of the UMR Gulliver 7083 located at the The City of Paris Industrial Physics and Chemistry Higher Educational Institution ESPCI.

My research areas are focused on the physics of complex fluids. In particular, I am interested in the behavior of polymers at interfaces, in the dynamics of wetting, and in capillary-gravity waves.
For my teaching activities at the ESPCI, see here .

Our work on capillary-gravity waves generated by a slow moving object has been featured in, see here

Our work on wave drag on floating bodies has been featured in, see here

Our work on Kelvin wake pattern has been featured in (see here) and in Le Monde, Science & Médecine (see here)

Our recent work on the Plateau-Rayleigh instability has been featured in Pour la Science (see here)

Our recent work on cooperative strings has been featured in Le Monde, Science & Médecine (see here) and in Pour la Science (see here)
