I am an Assistant Professor (Maître de Conférences) at the Department of Mathematics of Université Paris-Saclay. I am alos a member of the Inria Celeste team.
Before that, I was a postdoctoral researcher at EPFL in BAN chair. I did my PhD at Inria Paris under the supervision of Laurent Massoulié and Marc Lelarge.
Here is a short CV.
I am currently working on:
- Algorithmic fairness and causality
- Optimal transport for statistical learning
- Statistical inference in graphs and matrices
- Informational and computational thresholds for algorithms on random instances

- I am looking for a PhD student! Together with Evgenii Chzhen, we have a PhD offer at the interface between mathematical statistics and machine learning, namely about Handling unfairness in data: modelling, detecting, and debiasing. Have a look at the PhD proposal. Students are encouraged to apply by email.
- I recently gave an introductionary talk at IHES about Unsupervised Alignment of Graphs and Embeddings: Fundamental Limits and Computational Methods. [Youtube link].
