Baptiste Bergeot

Since September 2015, I work as an associate professor (maître de conférences) at INSA Centre Val de Loire (Blois, France). I do my research within the Laboratoire Gabriel Lamé (LaMé). Previously, I worked as a postdoctoral researcher with Prof. Bruno Cochelin and Prof. Sergio Bellizzi at the Laboratoire de Mécanique et d'Acoustique (LMA, Marseille, France). I hold a PhD from Le Mans University (Le Mans, France), which was supervised by Dr. André Almeida, Prof. Christophe Vergez and Prof. Bruno Gazengel.
