I am a Research Scientist (Directeur de Recherche, DR2) in the AnankΞ team at CMAP, École polytechnique, Inria Saclay. I am also a Professeur Chargé de Cours (PCC, 64h) at CMAP, École polytechnique since November 2024.

My research focuses on the mathematical and numerical design of digital twin based upon PDE-based models, with emphasis on:

• Wave propagation — asymptotic analysis of multi-scale and stiff wave problems, including elastic, electromagnetic, and hydro-acoustic waves
• Robust numerical methods — spectral element methods (SEM), implicit-explicit (IMEX) schemes, local time-stepping, high-order time discretizations
• Inverse problems & data assimilation — observer-based reconstruction, optimal control for medical imaging and non-destructive testing
• Applications — medical imaging (popularization article), ultrasonic NDT, ocean wave modelling
