Florian Feppon

I am a Hermann-Weyl postodoctoral instructor at ETH Zürich. I am mentored by Habib Ammari in the Seminar for Applied Mathematics.

My current research focuses on homogenization of wave metamaterials.

Before, I completed my PhD thesis at Centre de Mathématiques Appliquées (École polytechnique, Palaiseau) under the supervision of Grégoire Allaire and that of Charles Dapogny (Laboratoire Jean Kuntzmann, Grenoble) with a CIFRE funding provided by Safran.

And even before, I worked with Pierre Lermusiaux at Massachusetts Institute of Technology where I wrote a Master’s thesis on geometric methods for dynamical Model Order Reduction of Lagrangian transport.

A PhD thesis offer on October 1st 2022: Constrained optimization of nonlinear uncertain systems
