Present teaching activities

Despite a CNRS position, which means that teaching is not mandatory, I developed among the years a real interest in physics teaching at master lever. I list here only a couple of lecture I gave among the years.

  • Préparation à l’agrégation externe de sciences physiques option physique – ENS Paris-Saclay
    • Cours de mécanique des fluides [16 h/year]
    • Corrections de leçons et montages
  • Jury de l’agrégation interne de physique-chimie (2018-2022)
  • Formation mécanique des fluides à destination des professeurs·es- Académie Orléans-Tours [Poly]

Past teaching or related activities

The research theme of my work is the mechanics at interfaces and the role of the structure of this interface on the global behavior at the macroscopic scale. Among the diffferent projects that I have, I can cite.

  • The mechanical properties of the solid-fluid interface. The question that interests me is how simple or complex fluids slip on the walls and what are the mechanisms of transmission of interfacial stresses. For example, in the last few years, I have been working on the slip of polymer melts and solutions (together with Liliane Léger (thanks to her!, Elisabeth Charlaix and Josh-Mc Graw): role of the nature of the interface, role of the structure of the interface, influence of molecular parameters, influence of temperature. In collaboration with François Boulogne and Emmanuelle Rio we have extended this question to the problem of the friction of liquid foams on solids. I have recently collaborated with Vincent Mathieu and Isabelle Souchon (INRAE, Grignon) on the question of the interface between food gels and rough surfaces. Even more recently, together with Alexis Chennevière (LLB CEA), we extended our study of the case of solid-polyionic liquid interfaces.
  • The mechancial properties of the fluid-gas interface. A second type of interfaces for which I study the mechanical properties are the liquid-air interfaces in the presence of surfactants. To be more precise, the question we are trying to address is the question of the generation and death of soap films and the role of the interface in these two phenomena. I started this work when Emmanuelle Rio joined the LPS, as it was a continuation of my post-doc work with David Quéré. Recently, we have been focusing on two issues: the role of evaporation, and the problem of entrainment at high capillary and Reynolds numbers by building in particular a device for automatic production of giant soap films.
  • The mechanical properties of the solid-solid interfaces. After having worked for several years on adhesion and friction problems on textured surfaces with Christophe Poulard, we have undertaken a systematic study of the role of adhesion and friction in interleaved systems.

Overall, my profile is that of an experimental physicist, interested in taking physical chemistry into account. We develop original experimental devices.
