I am a PhD student working under the supervision of Jérôme Bolte at Université Toulouse 1 Capitole and Alexandre d'Aspremont within the SIERRA team in Paris.

I currently focus on algorithms for large scale optimization problems, with a special interest for non-Euclidean gradient methods.

More details can be found on my résumé.
