Alexandre RENAUX

I got the Ph.D. degree in electrical engineering from Ecole Normale Supérieure de Paris-Saclay (formerly Ecole Normale Supérieure de Cachan), France, in 2006. From 2006 to 2007, I was a postdoctoral research associate at the Department of Electrical and Systems Engineering, Washington University in St. Louis, MO, USA. Since 2007, I teach at the Physics Department (Faculté des Sciences) of Université Paris-Saclay, France and my research lab is the Laboratory of Signals and Systems located at CentraleSupelec (Université de Paris-Saclay). From September 2020 to August 2021, I was on leave at the Universidade Federal do Espírito Santo (UFES), Vitória, ES, Brazil. My research interests are in the field of statistical estimation and lower bounds on estimation errors in the context of machine learning and signal processing.
