I am a senior researcher (DR2) with the CNRS, at the Computer Science Department (LIP6, APR team) of Sorbonne Universite. I am also a professor (PCC) at Ecole Polytechnique. My research focuses on Topological Data Analysis and Visualization.
I am the principal investigator of the project TORI (In-situ Topological Reduction of Scientific Data), awarded by the ERC.
