Research

Post-doc in ecotoxicology, as part of the EXTREMES project, coordinated by INRAE and Inserm. I'm working in collaboration with Marie-Agnès Coutellec and Scott Mc Cairns. Our study focuses on the impact of heavy metals in a realistic multi-exposure context, combined with the influence of climate change and the genetic origin of populations, on the growth of the pond snail, Lymnaea stagnalis. This project has an eco-evolutionary dimension and proposes to study these impacts on the mechanisms underlying the growth response, at the transcriptomic level.

Expertise

I'm a biologist with a particular interest in the phenotypic adaptations of individuals to various environmental disturbances. 

I have worked with vertebrate models (marine and freshwater fish) and invertebrates (crustaceans and molluscs). I worked as an ATER at the University of Caen Normandie, giving a full teaching service and studying the behavioural and physiological responses of crayfish, Procambarus alleni to looming stress in collaboration with Dr. Julien Bacqué-Cazenave and Roman Coupeau. I have also worked on the evaluation of personality traits in relation to learning abilities in the crab, Hemigrapsus sanguineus, with Dr. Cécile Bellanger and on setting up experimental protocols to evaluate the energy metabolism of eggs in the cuttlefish Sepia officinalis, exposed to drug pollution in the Seine estuary and to global change with Salomé Brousseau.

Prior to this, I was a post-doc in Dr. Vishwesha Guttal's lab at the Indian Institute of Science. We used empirical and theoretical approaches to study the inter-individual interactions involved in information transfer during collective threat avoidance in a school of fish. This collaborative project with Dr. Guy Theraulaz from the CNRS was funded by CEFIPRA and an IISc Excellence Fellowship, IOE. My PhD at the Université de Bretagne Occidentale focused on the behavioural and physiological response of fish to various changes in environmental conditions (food shortage, oil spill, hypercapnia). I examined individual and social behaviours as well as individual energy metabolism as indicators of the health status of animals exposed to these environmental disturbances. As part of my Master 2 project, I studied the impact of sound vibrations linked to anthropogenic activities at sea, on the physiology and behaviour of the shore crab, Carcinus maenas, and the common mussel, Mytilus edulis.
