My research interests include optimization for (graph) signal processing and machine learning, algorithmic differentiation and the use of sparsity in these domains. I am currently PI of the ANR JCJC GraVa, dedicated to a subset of these research topics.
Previously, I was a postdoc at CMAP, the applied math institute of École Polytechnique, under the supervision of Antonin Chambolle during the academic year 2014-2015. Before that, I did my PhD at CEREMADE (Univ. Paris-Dauphine) under the supervision of Gabriel Peyré.
My PhD students are
- Quentin Klopfenstein (2018-2021?), co-supervised with Hervé Cardot;
- Hashem Ghanem (2020-2023?), co-supervised with Nicolas Keriven and Joseph Salmon;
- Adrien Frigerio (2020-2023?), co-supervised with Hervé Cardot and Xavier Dupuis.
