Florian Feppon

I am an assistant professor in the NUMA division of the Computer Science Department of the university of KU Leuven. I have broad interests in the fieds of Uncertainty Quantication, Data Assimilation, Optimal design, analysis of Partial Differential Equations. My research aims notably at bringing top of the art mathematics to the service of the industrial applications.

From 2020 to 2022 I was a Hermann-Weyl postodoctoral instructor at ETH Zürich. I was mentored by Habib Ammari in the Seminar for Applied Mathematics.

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.
