Presentation

Welcome to my webpage. My research areas are the calculus of variations, elliptic PDEs and geometric measure theory. I am interested in the uniqueness, regularity, and qualitative properties of solutions to minimization problems in the calculus of variations or elliptic PDEs, Gamma-convergence for phase fields or homogenization.

Since September 2024, I am a maître de conférences (associate professor) at the université de Nîmes, working in the Laboratoire mathématiques, informatique, physique et applications (MIPA). Previously, I worked in the Institut de recherche en mathématique et physique (IRMP) of the UC Louvain as a Postdoctoral researcher under the supervision of Heiner Olbermann.

My Ph.D. was defended in July 2023 and supervised by Pierre Bousquet at the Institut de Mathématiques de Toulouse.

I am the organizer of the MIPA seminar.

This webpage gathers information and documents about my research and teaching activities as well as my educational background.
