Au Département de Physique de l'Université de Montréal, je suis professeur adjoint en Physique des plasmas appliqués à la synthèse/fonctionnalisation des nanomatériaux et au traitement des liquides.

Je m'intéresse aux plasmas à la pression atmosphérique et aux interactions plasmas-matière, en particulier celle qui est en phase liquide. Dans ce contexte, mes activités de recherche sont subdivisées en trois axes :

• plasma en contact avec un liquide,
• plasma dans un liquide et 
• plasma dans un milieu diphasique (par exemple mélange de deux liquides immiscibles ou mélange air-liquide, c.à.d. bulles). 

En plus de la compréhension fondamentale de la science de cette nouvelle famille des plasmas, je développe des applications originales, innovantes et prometteuses. Bien que le champ d’application soit extrêmement large, je m’intéresse à court terme à appliquer les plasmas en phase liquide dans la stérilisation des eaux, la synthèse des nanomatériaux et la production des carburants propres.

Bien que le champ de recherche '' plasma-liquide '' est relativement nouveau, les premiers résultats ont montré qu'il y a une très belle physique à explorer et un potentiel énorme pour résoudre des problématiques sérieuses au niveau mondial.
