2000: PhD in Hydrobiology, University of Toulouse III, France

Professional experience

2004-present: Assistant Professor, University of Toulouse III, France


Ozenne Prize of the “Académie des Sciences, Inscriptions et Belles Lettres de Toulouse” (2002)

My research theme aims at determining how species introduction can influence the functioning of aquatic communities. Interactions between native and exotic fish species and their consequences on communities are still poor understood. I assess the trophic interactions between top-indigenous and exotic predators, and their impact on the structure of aquatic food webs. I seek to identify sources of carbon (13C) and trophic levels (15N) involved in the biological interactions, in order to identify the influence of introductions of exotic species on : i) the niche trophic overlap / shift between native and introduced species, and ii) the carbon flow in food webs

Project management

Since 2004, I have been the principal investigator of 20 national and international research projects.
