Presentation

Après une thèse au [CEA - Leti](https://www.leti-cea.fr/cea-tech/leti) à Grenoble entre 2017 et 2020, j'ai effectué un postdoc au sein du [groupe Crypto](https://www-crypto.elen.ucl.ac.be/crypto/) de l'[Université catholique de Louvain](https://uclouvain.be) (Louvain-la-neuve, Belgique). Je suis désormais chargé de recherche [CNRS](https://cnrs.fr) au sein de l'équipe [SmartIES](https://www.lirmm.fr/equipes/smarties/) du [Laboratoire d'Informatique, de Robotique et de Microélectronique de Montpellier](https://www.lirmm.fr/) (LIRMM). Ma recherche porte sur l'analyse des attaques par *canaux auxiliaires* contre les implémentations d'algorithmes de chiffrement. Je m'intéresse en particulier à l'usage des techniques d'apprentissage machine appliqué à une classe d'atttaques spécifiques : les attaques par *profilage*.
