About me
I’m a 3rd year PhD Student in Applied Mathematics at Centre Borelli (ENS Paris-Saclay) under supervision of Nicolas Vayatis. My PhD is funded through a CIFRE fellowship with Framatome, a world leader in civil nuclear industry. My research sits at the intersection of machine learning and optimal control, with a focus on developing algorithms that are both faster and more accurate in demanding industrial settings. I am particularly interested in how modern ML frameworks can address the computational challenges that arise in real-world control problems.
All my publications are listed here and on my Google Scholar.
