Publications

This page lists my scientific publications and ongoing work. Most of my research focuses on embedding physical priors into neural network architectures for interactive physical simulation in virtual reality. They stem from my work at CEA-List, with the exception of the NeurIPS workshop (EDF research internship) and the NLP publication (freelance mission).
