Irène Waldspurger obtained a master's degree in fundamental mathematics, then prepared a Phd in signal processing and machine learning at École Normale Supérieure de Paris, under the supervision of Stéphane Mallat. She defended it in 2015 and subsequently spent a year as a postdoctoral fellow at MIT, mentored by Philippe Rigollet. Since 2017, she is chargée de recherche at CNRS, affiliated with Ceremade (Paris Dauphine) and the Inria team Mokaplan.
