Thématique(s) de recherche

Diversité, structure, fonctionnement des réseaux trophiques microbiens lacustres en réponse aux forçages anthropiques et climatiques
Questions abordées : Etude (i) de la diversité des communautés planctoniques (ii) des interactions et transferts trophiques s'établissant dans les réseaux planctoniques (iii) des facteurs de régulation qui affectent la dynamique, la structure, la diversité et l'activité des micro-organismes planctoniques.

Approches et outils : Approches limnologiques et paléolimnologiques, Approches expérimentales en microcosmes, mésocosmes ; et ADN environnemental (qPCR, séquençage massif & metabarcoding, FISH).
