Present affiliation: permanent research and teaching position at University of Geneva, Section of mathematics.

Summary.
I am a senior lecturer (Maître d'enseignement et de recherche) at University of Geneva, Section of Mathematics.
I received my PhD in Mathematics in 2008 from the University of Rennes 1 (France, National Institute for Research in Digital Science and Technology) and the University of Geneva (double doctorate program). Before joining the University of Geneva in 2013, I was a post-doctoral researcher at the Swiss Federal Institute of Technology, Lausanne and agrégé-préparateur at the École Normale Supérieure de Rennes where I obtained my Research Habilitation in 2013.
My research focuses on the numerical analysis of geometric and multiscale methods for deterministic or stochastic (partial) differential equations, with special emphasis on geometric numerical integration methods with related algebraic structures, and numerical homogenization methods for highly oscillatory problems.
In 2013, I received the Young Researcher First Prize 2013 (Mathematics) of the Region Bretagne (France).

Former affiliations: Ecole Polytechnique Fédérale de Lausanne (EPFL), Université de Rennes 1 (IRMAR), INRIA Rennes (IPSO), Ecole Normale Supérieure de Rennes.

We organize the numerical analysis seminar together with Martin Gander and Bart Vandereycken.
I am a member of the Swiss mathematical society, Swiccomas, and SMAI (France).
I am a member and co-founder of the CAMAS Consulting platform (Section of Mathematics, University of Geneva).
I am a member of the advising committee for studies in Mathematics, Computer Sciences and Numerical Sciences (Bachelor and Master).
