Ludovic Rifford obtained his doctorate, which he prepared under the supervision of Francis Clarke, at the Université Lyon 1 in 2000. After holding assistant professor positions at the Lyon 1 and Paris-Sud (Orsay) universities, Ludovic Rifford took up a professorship at the Université Nice Sophia Antipolis in 2006 (recently renamed the Université Côte d’Azur). During his career, he has been interested in various problems at the interface between analysis, dynamics and geometry. He has largely contributed, inter alia, to major advances in two important conjectures of sub-Riemannian geometry (the so-called Sard conjecture) and Hamiltonian dynamics (the Mañé conjecture). He is the author of fifty or so articles and a monograph, and counts two Fields medallists (Cédric Villani and Alessio Figalli) among his regular co-authors. In addition, Ludovic Rifford was a junior member of the Institut Universitaire de France from 2011 to 2016, Eisenbud Professor at the Mathematical Sciences Research Institute, Berkeley in the autumn of 2013 and Distinguished Guest Professor at the Center for Mathematical Modeling at the University of Chile, Santiago, from February to August 2015. Deeply involved in cooperation activities, he served as Executive Director of CIMPA from September 2016 to September 2020 and has been Secretary for Policy of the Commission for Developing Countries of the International Mathematical Union since January 2023. Currently, Ludovic Rifford holds a CNRS-AIMS Chair under the CNRS-Africa Joint Research Program for the period September 2023 – September 2027.
