Présentation

Après un DEA de Physique Théorique en 1994, je me suis spécialisé en Physique Numérique (Computational Physics) dans le domaine de la modélisation et de la simulation en nanophotonique. Je suis devenu Maître de Conférences en 1998, puis Professeur des Universités en 2004 à l’Université Montpellier 2.

Mes préoccupations sur le numérique au service de la formation m'ont amené au fil du temps à assurer différentes missions : chargé de mission TICE, Assesseur TIC, Vice-Président d'Université et de COMUE, Vice-Président puis Président du GIP FUN-MOOC, Président du GIP France Université Numérique.

Depuis janvier 2019, je suis Vice-Président délégué au Numérique pour la Formation de l’Université de Montpellier.

En 2004, j'ai créé le parcours Physique Numérique du Master de Physique de la Faculté des Sciences et j'en suis actuellement coresponsable.

Par ailleurs, je m'intéresse aux interactions Sciences et Citoyens et aux actions de Culture Scientifique. J'ai notamment créé le Bar des Sciences de Montpellier en 1999 et je l'ai animé pendant 7 ans (60 rencontres).
