Activité de recherche

Je travaille en physique théorique de la matière condensée. Mes activités de recherche sont centrées autour des systèmes dits à fortes corrélations électroniques. Je m’intéresse tout particulièrement au développement de méthodes permettant de décrire de tels systèmes à partir des premiers principes.
