Présentation

Professeur en informatique à l'université de Lille. Je suis membre du laboratoire CRIStAL . Je dirige l'équipe Magnet..

Depuis 2015, mes recherches portent sur l'apprentissage automatique et les réseaux d'information, ainsi que sur l'apprentissage décentralisé et l'apprentissage automatique préservant la confidentialité. Auparavant, j'ai travaillé principalement sur les automates d'arbres et les contraintes entre 1990 et 2000, puis sur la classification, l'apprentissage automatique et l'extraction de données et d'informations structurées (2000-2015).
