Biography

I am an experimental physicist working on interfacial flows and dynamics. In particular, I am interested in the stability of soapy objects like foam films, bubbles or foams. This includes flow at interfaces, dynamic interfaces and their mechanical properties, or macroscopic behavior of soapy objects.

Interests

  • Foams, bubbles and soap films stability
  • Surface rheology
  • Thin film thinning, drainage and evaporation

Education

  • PhD in Hydrodynamics, 2005, Paris 6 University
  • Accreditation to direct research (HDR), 2013, Paris Sud University

Professor in Paris Saclay University

Head of the track « Soft Matter and Biophysics » in the ICFP Master 2

Lecture in Complex Fluid and Interfaces in the Master 1 in fundamental physics

Lecture in Interfacial flows in the Master 2 DFE

Teaching about the scientific approach in the first year of physics licence
