I am interested in the behaviour of solutions of the wave and Schrödinger equations in chaotic environments. I try to understand to what extent these solutions present characteristics of delocalisation and randomness. The quantum ergodicity phenomenon is an example of delocalisation of these solutions when the underlying dynamics are ergodic. My research covers different types of geometry: discrete and continuous. The behaviour of waves is closely related to the geometry of the surface, space or network on which they evolve. Understanding these interactions is one of my main goals.
