Professional positions:

  • UPS, Engineer, Functional Ecology and Environment Laboratory - UMR 5245 (France; 2006-present).

Academic background:

  • 2007- Ph.D. Toulouse III University, EcoLab (France): Ecology of the zooplankton of the Scheldt estuary (Belgium).
  • 2001- Master degree. Toulouse III University, CESAC (France), Study of the predation impact of the palmate newt (Triturus helveticus) and the notonect (Notonecta maculata) on a natural population of zooplankton.

Research area: Biodiversity and Freshwater ecology

My goal is to investigate the freshwater diversity in relation with environmental pressures and changes. In this context, I am interested by the trophic interactions. My study models are diverse, from the zooplankton to fishes.

My works realized in collaboration with French and foreign colleagues are based on both laboratory and in situ experiments and on field observations, including scientific scuba diving.

  • Responsible of the Scientific SCUBA diving team of EcoLab, since 2007.
  • Responsible of the Biologic analyses service.
  • Responsible of the microscope labs.
  • Co-responsible of the project RECIF LOT ; 2013-2015.
  • Member of the laboratory board, since 2007.
  • Member of the laboratory informatic commission.
  • Member of the health and safety commission (4R1 site).
