> Research interrests

My research focuses on ecophysiology of zooplankton organisms (like appendicularians, planktic foraminifers or more recently jellyfishes and salps) that play a major role in carbon transfer to the ocean floor. My research works aims to quantify how environmental factors influence these organisms physiology and how this physiology constrains the organism growth, abundance and action on carbon fluxes and on the ecosystem. In extension, I also search to understand the fate of detritus particles produced by those organisms. My research work combines experimental, modeling and data analysis works and uses several pluridisciplinary fields such as physiology, behavioral ecology, biogeochemistry, biogeography and micropaleontography.

> Current work

Funded by the French ANR “post-doc return” EcoGely

This project aims are to determine how environmental conditions constrains gelatinous zooplankton physiology, biology and proliferations. In turn it also aims to understand the action of gelatinous zooplankton on matter fluxes and on the ecosystem. My project suggest to focus on two type of organisms representative of predators (Pelagia noctiluca) and filter-feeders (salps Salpa fusiformis and Thalia democratica) which are both abundant in the Mediterranean Sea.
