My research lies in numerical methods for nonlinear evolution PDEs, with an emphasis on the design and analysis of time-integration methods for solving dispersive equations in low-regularity spaces.
I obtained in 2024 an NSF Postdoctoral Fellowship Award. I am starting my postdoc at the Institut de recherche mathématique de Rennes (IRMAR) in France, and then at the MIT with Gigliola Staffilani.
I completed my PhD at the Laboratoire Jacques-Louis Lions (Sorbonne Université) in Paris, France, under the supervision of Katharina Schratz.
Before that, I received a two-years schorlarship from the Paris Graduate School of Mathematics (PGSM) to complete the master's program M1/M2 Mathématiques de la Modélisation at Sorbonne Université/Paris 6.
I completed the bachelor's degree at McGill University and at l'Université de Montréal in Montréal, Canada.
