Alexandre RENAUX

I studied electrical engineering at école normale supérieure de Paris-Saclay (formerly école normale supérieure de Cachan), France, from 1999 to 2006 -B.Sc., M.Sc., Agrégation (a French stuff), and Ph.D.- From 2006 to 2007, I was postdoc researcher at Washington University in St. Louis, MO, USA. Since 2007, I teach at Université Paris-Saclay (formerly Université Paris-Sud), France and my research lab is the laboratory of signals and systems located at CentraleSupelec. I'm interested by/in noisy electrical signals parameters estimation (mainly the calculus of statistical errors).
