Quantum chaos, semiclassical limit of quantum mechanics. Dissipation and decoherence.
Most of my research deals with the dynamics generated by chaotic maps or flows, together with their quantizations.
I co-organized a Quantum Chaos Summer School at the Erwin Schrödinger Institute in August 2012.
Lectures on Spectral theory of damped quantum chaotic systems I gave in June 2011.
Lectures on the Theory of dynamical systems I gave in 2009.
I am currently editor of Nonlinearity.
I am co-coordinator of the Groupe De Recherche (Research group) Quantum Dynamics, and member of the research project Spectral Geometry, Graphs and Semiclassics (GeRaSic) funded by the Agence National de la Recherche.
