About Me

I'm a PhD candidate in Applied Mathematics at École Polytechnique (Centre of Applied Mathematics) and the French Atomic Energy Commission (CEA).

My research focuses on developing a methodology for uncertainty quantification, with the goal of improving the accuracy and predictivity of fluid-structure interaction simulations in nuclear reactors.

Along the way, I've built an experience in: Statistics, Probability, Mechanics, Thermal-hydraulics, Neutronics, Numerical methods

Beyond my core research, I'm also very interested in quantitative finance, especially in roles that involve quantitative research and data-driven decision-making.

My PhD is directed by Professor Josselin Garnier and supervised by Bertrand Leturcq and Stanislas de Lambert, researchers at the CEA.
