I am current a Tenure-Track Assistant Professor at Ecole Polytechnique, IP Paris. Prior to that, I was a postdoc researcher at @VISTA Team, LIX, Ecole Polytechnique, working with Vicky Kalogeiton. I finished my Ph.D. at Univ Rennes 1, Inria Rennes and IRISA advised by Marc Christie and Eric Marchand. My main research interests lie in generative models, 3D vision and computational cinematography.
