Within the Statistical Physics Laboratory at ENS, these methods are largely applied to domains belonging more directly to the physics of disordered systems and of growth and form.
We make use of both analytical and numerical techniques. In addition, an experimental psychology activity is being developped in parallel to our modeling approach in cognitive sciences.
