Ce professeur désire s'entretenir avec les médias

Je m'intéresse aux relations entre les communautés microbiennes et leur environnement, ainsi qu'aux interactions des populations microbiennes entre elles au sein d'un habitat. Pendant mon doctorat (IFREMER, France) et mon premier post-doctorat (Université de Caroline du Nord, USA), j'ai étudié la diversité et métabolismes des communautés microbiennes dans les habitats de la subsurface marine. Depuis mon deuxième post-doctorat (Université Friedrich-Schiller, Allemagne) et mon poste de Professeure au département des Sciences Biologiques à l'UQAM, je m'intéresse aux habitats souterrains terrestres, que ce soit la subsurface superficielle ou profonde. Mes autres intérêts sont les habitats aquatiques (de surface ou souterrains), et les populations microbiennes qui vivent dans l'abdomen des insectes.
