After completing my PhD in ecotoxicology at the National Research Institute of Science and Technology for Environment and Agriculture (Irstea, France), I integrated the National Institute of the Scientific Research (INRS, Canada) as molecular biologist. My research interests include the study of the links between contaminant exposure and responses of ecosystems in the face of global changes, especially using diatoms, cyanobacteria and periphyton as biological models.
Since 2016, I have been employed at the National Museum of Natural History (MNHN, France). My work is part of the project CYPHER (CYanobacterial toxin production and PHotoprotection processes in a changing EnviRonment- ANR-15-CE34-0002) that aims to understand the relations between cyanotoxin synthesis, photosynthesis and photoprotection. My contribution to this program concerns the characterization of the transcriptomic and metabolomic responses of Planktothrix under stress conditions.
