Florian Feppon

I am a postdoctoral researcher under the supervision of Grégoire Allaire at Centre de Mathématiques Appliquées (École polytechnique, Palaiseau). I completed my PhD thesis under his supervision and that of Charles Dapogny (Laboratoire Jean Kuntzmann, Grenoble) with a CIFRE funding provided by Safran. My research focuses on topology optimization of multiphysics systems with the level set or the homogenization method.

Before, I worked with Pierre Lermusiaux at Massachusetts Institute of Technology on geometric methods for dynamical Model Order Reduction of Lagrangian transport.
