I am a Senior Scientist at valeo.ai in Paris and a member of the Inria–Valeo ASTRA team. A graduate of École Polytechnique, I received my PhD from LIGM (École des Ponts, Université Paris-Est), under the supervision of Renaud Marlet, on automatic building reconstruction. I then spent several years as a researcher at ONERA, working on remote sensing and scene understanding from 3D lidar point clouds. My research currently focuses on machine learning for autonomous driving, from 3D lidar perception to image-based end-to-end driving.
