Gilles Chardon

I am associate professor at CentraleSupélec with the Laboratoire des Signaux et Systèmes (L2S). In a past life, I was postdoc at the Acoustics Research Institute in Vienna, Austria. In a past life of order 2, I worked at Institut Langevin, where I was PhD student with Laurent Daudet. My thesis is here (in french).
