**Intérêts**: Mes travaux de recherche portent sur les thèmes: Localisation des Ondes, Chaos Ondulatoire et Propagation d’Ondes en Milieux Complexes. Ils concernent les propriétés des ondes, essentiellement classiques (optique, micro-onde, acoustique, vibratoire), en milieux hétérogènes ou confinés. **Publications**: Plus de 50 publications dans des revues à comités de lecture Referee for Physical Review Letters, Physical Review A, B, E, Journal of Physics A, IEEE EMC Transactions. **Membre de la Société Française de Physique**
**Interests**: Propagation of waves in complex media, Wave chaos in multimode optical fibers, Multiple scattering and localization with microwaves. Wave chaos in electromagnetic reverberation rooms for EMC, Random Matrix Theory (RMT), Effective Hamiltonian Formalism, etc. **Publications**: More than 50 refereed publications Referee for Physical Review Letters, Physical Review A, B, E, Journal of Physics A, IEEE EMC Transactions. **Member of the Société Française de Physique**
