Research topics :
I am a zooplankton ecologist, assistant professor at the University of Montpellier. My research activities focus on both fundamental and applied topics :
• Exploring how climate changes modify marine planktonic communities and trophic food webs
• Understanding gelatinous plankton life cycle and responses to environmental changes
• Quantifying and characterizing marine microplastic pollution and investigating its role in the first trophic levels of marine food webs
