R&D engineer at Eurobios Scientific Computing Branch.
My field of work is scientific computing, applied mainly to computational fluid dynamics for multiphase flows and free-surface flows.
I have recently been working on the use of machine learning for the design of numerical schemes for PDEs. In particular, I worked on the use of neural networks as volume-of-fluid schemes for the Finite Volume numerical simulation of multiphase flows.
Previously, I’ve worked on the numerical simulation of floating bodies (and in particular wave energy converters) using linear potential flow models solved with the boundary elements method (BEM). I have released the software Capytaine which is a rewrite of the the open source code Nemoh with a Python user interface.
Before that, I have worked on the numerical simulation of wave impacts with phase change using finite volume schemes for conservative and non-conservative hyperbolic problems. This work was applied to the study of sloshing in floating LNG tanks.
