Research topics

My research fits in the domain of numerical analysis for PDEs. The work done during my PhD and post-doctorates concerned the development of numerical methods for the simulation of multi-component flows. Since I arrived in Centrale Nantes, my research work has mainly focused on the development of approximation and model order reduction methods for partial differential equations using either deterministic and probabilistic approaches.
