ABOUT ME
I'm a young researcher interested in aquatic ecosystems monitoring and fish species conservation. I studied marine sciences during my Bachelor and Master degrees then my PhD and postdoc works were freshwater ecosystems centered. For a few years, I work in close collaboration with environmental managers to apply my research work to environmental monitoring, population dynamics and conservation biology.
RESEARCH & EDUCATION
RESEARCH INTERESTS
Population dynamics and conservation biology
Funded by the French National Agency for Water and Aquatic Environment (ONEMA), we assess abundance, biomass and fish length trends of most common fish species in France over the last 22 years. Our work aims at detecting declining species or life-traits related to species declines to improve river conservation and management.

A biomarker of genotoxicity in three-spined stickleback (Gasterosteus aculeatus): application to environmental monitoring and predictive value in Ecotoxicology
Supervision: Dr. Alain Devaux and Dr. Wilfried Sanchez
Environmental monitoring, ecological risks assessment and reproductive toxicology
In the European Water Framework Directive context which aims at reaching the good chemical status of European water bodies, we investigated a battery of biomarkers in a fish species to assess ecological risks of river contamination for fish populations. We focused our work on a genotoxicity biomarker and demonstrated the relationship between fish parental exposure to genotoxicants and detrimental effects transmitted to their offspring which could lead to long-term population disturbances.

Marine Sciences and Coral reef species ecology
Thanks to my master degree and my research projects in marine biology, I get in-depth knowledge in marine and coastal environmental sciences.
Objectives of my research project in French Polynesia were the identification and description of Crustacea species captured as post-larvae during coral reef post-larval colonization. We aimed at understand reef colonization patterns linked to environmental factors (lunar cycle) to apply our scientific finding to aquaculture. The final goal of this work was to capture valuable Crustacea species before early life stage mortality to develop aquaculture projects and thus, to protect natural adult fisheries.
My study on the marine fish Dicentrarchus labrax embryo-larval development aims at describing key stages during early life stage development.
Marine sciences and aquaculture
Ecotoxicology, ecology and conservation biology
Master courses focused on ecology and conservation biology gave me a scientific background and awareness in conservation biology I nowadays use working in collaboration with environmental managers.
My research project trained me to aquatic ecotoxicology and genotoxicity biomarkers. We also developed the assessment of hydrolase epoxide activity as a new biomarker of fish exposure to PAH.
