Welcome to my website!

I am currently a scientific researcher (Chargée de recherche) at the Inria center University of Lorraine and antenne University Strasbourg in the MACARON research team (formerly TONUS) seated at IRMA of the University Strasbourg.

My research interests are in numerical methods for hyperbolic systems. In particular

• Computational Fluid Dynamics for atmospheric flows, multi-phase flows and multi-material interactions
• Robust numerical methods with the focus on all Mach number schemes using implicit and semi-implicit/implicit-explicit methods
• Structure preserving numerical schemes with the focus on well-balancing, asymptotic preserving property, entropy stability, thermodynamic consistency and involution constraints
• High order finite volume methods involving time-limiting TVD-MOOD strategies
