Biography

I am Directeur de Recherche CNRS at LIRIS in the Origami team. Director of the Groupement de Recherche (GdR) Informatique Géométrique et Graphique, Réalité Virtuelle et Visualisation. Co-lead of the PEPR ICCARE. General chair of the Graphics Replicability Stamp Initiative. Co-founder of the DGtal library. My main focus is digital geometry, geometry processing and point sampling for Monte Carlo rendering.
