Since November 2016, I am a postdoctoral researcher working on random matrices at Saarland University within the free probability research team of Prof. Roland Speicher. Before I was a CNRS postdoc at Télécom ParisTech under the supervision of Prof. Walid Hachem. In Spetember 2015, I obtained my PhD degree from Université ParisEst, supervised by Prof. Florence Merlevède and Prof. Emmanuel Rio.
