My research focusses on the modelling and analysis of the
nonlinear dynamics of extended fluid systems.
The focus is on the transition towards spatio-temporal complexity and
turbulence. However, recently, I also decided to study developed turbulence.
From a theoretical point of view, all these systems are ruled
by nonlinear partial differential equations
issuing from theories such as the thermomechanics or the physics of fluids.
In order to solve them, I develop semi-analytical methods
(linear and weakly nonlinear stability analyses,
reduction to generic amplitude equations or envelope equations, etc...)
and numerical methods
(Galerkin methods, spectral methods, etc...).
I also try to interpret the mechanisms driving the observed scenarios.
I present on web pages the results of such works with colleagues, essentially, in Lemta, on convection instabilities in nematic liquid crystals, systems presenting nonlinear waves and flows in shear-thinning fluids. Recently, we also focussed on plasma instabilities and turbulence models.
Researcher since 1993, I published, with some colleagues, a few articles.
Former PhD students (co-direction with Jean-Pierre Brancher then Chérif Nouar and Christel Métivier) are
