Samuel Vaiter

Research Scientist (CR)

CNRS

I am a CNRS research scientist (Chargé de Recherche) in Applied Mathematics at IMB (Univ. de Bourgogne, France). I am a member of SPOC research team (Statistics, Probability, Optimization and Control). Previously, I was a postdoc at CMAP, the applied math institute of École Polytechnique, under the supervision of A. Chambolle during the academic year 2014-2015. Before that, I did my PhD at CEREMADE (Univ. Paris-Dauphine) under the supervision of G. Peyré.
