Hello! I recently completed my PhD in Reinforcement Learning at Université Paris-Saclay, where I worked on Learning-based Control of Dynamical Systems with applications in Computational Fluid Dynamics. My research was supervised by Anne Vilnat, Onofrio Semeraro, and Lionel Mathelin. My PhD thesis is available here.

Before, I was a research intern at Inria TAU, where I worked on Learning-based methods for Stiff Differential Equations: Koopman operator theory and Physics-Informed Neural Networks (PINNs) under the supervision of Michele-Alessandro Bucci, Thibault Faney, Cédric Mehl and Marc Schoenauer.
I have also been a research intern in several R&D departments such as Capital Fund Management (CFM) (Anomaly Detection in Time Series), BNP Paribas Real Estate (Machine Learning for Real Estate Market Analysis), and Luxurynsight (Deep Learning for Natural Language Processing).

I hold an MSc in Artificial Intelligence, Systems, and Data (IASD), an MSc in Statistics and Financial Mathematics and a BSc in Applied Mathematics (probability and statistics) at Université Paris Dauphine - PSL.
