Current Position

Maître de Conférences (~reader) at the Université d’Avignon (France).

Main Scientific interest

My scientific research is directed towards the understanding of the spontaneous pattern formation in fluids analyzing the dynamics of nonlinear systems.

The spatial or/and temporal structure is known to result from a spontaneous symmetry-breaking.


To study the dynamics scenarios, I am using theoretical tools of equivariant bifurcation theory and I am developing numerical tools for time-integration, continuation methods and bifurcation analysis.

These methods are applied to hydrodynamical system with spherical symmetry (Rayleigh-Bénard convection in geophysical framework) and also on pattern formation of thin liquid layers (Galilean group symmetry).

Recently, I am applying this numerical tools to the transport in porous media in which intermittencies and fingering may be also explained as a spontaneous symmetry-breaking even the randomness of the medium.

Understanding the competition between randomness and pattern formation motivates my further work.
