Ioannis Mitliagkas

Ioannis Mitliagkas est professeur adjoint au Département d’informatique et de recherche opérationnelle (DIRO) de l’Université de Montréal. Auparavant, il a été boursier postdoctoral au Département de statistique et d’informatique de l’Université Stanford. Il a obtenu son doctorat au département de génie électrique et informatique de l’Université du Texas à Austin. Ses recherches portent sur les problèmes d’apprentissage statistique et d’inférence à grande échelle, sur les algorithmes efficaces à grande échelle et distribués, sur les garanties théoriques et dépendantes des données et sur les systèmes complexes d’optimisation.
