Je suis professeur à l'ENSTA Paris, membre de l'équipe Dynamique des Fluides et Acoustique de l'unité de Mécanique de l'ENSTA Paris.

Activités de recherche et de formation

Mes activités de recherche portent sur la dynamique non linéaire des systèmes mécaniques et plus particulièrement les vibrations non linéaires de structures minces.

Je travaille sur le développement de méthodes pour la réduction de modèles en vibrations non linéaires géométriques, et plus particulièrement sur les méthodes se fondant sur la théorie des variétés invariantes. Nous étudions aussi la transition vers la turbulence d'ondes et la caractérisation du régime turbulent pour les structures minces en grande amplitude, ainsi que la mise au point de techniques innovantes pour le contrôle passif et l'atténuation vibratoire, en utilisant des amortisseurs non linéaires ou en ajoutant des non-linéarités pour améliorer l'effet trou noir acoustique.
