Short Bio

I graduated from Ecole polytechnique (Palaiseau, France), and obtained the « Mathématiques, Vision, Apprentissage » (MVA) Master’s degree from Ecole Normale Supérieure de Cachan in 2014. I prepared my PhD thesis at IRISA, Rennes, France, under the supervision of Rémi Gribonval, and defended it in October, 2017. From 2017 to 2019 I was a postdoctoral researcher at Ecole Normale Supérieure with Gabriel Peyré, on the CFM-ENS “Laplace” chair in data science, before joining CNRS in 2019 as a full-time researcher. I received the Best Student Paper Award at SPARS 2017 and the Early Career Prize of the SIAM Activity Group on Imaging Science in 2022. I am the PI of ANR JCJC GRandMa, starting in 2022.

I play the piano here and here.
