What if an invasive rodent could tell us which chemicals circulate in our environment, and potentially reach our food? LIGER-EXPO uses the coypu (Myocastor coypus) as a sentinel species to characterise exposure to pesticides, POPs, PFAS and emerging contaminants across the Pays de la Loire region, within a One Health framework. 

You will:
▪️ develop targeted and non-targeted LC/GC-HRMS methods for internal matrices (liver, adipose tissue)
▪️ evaluate non-invasive matrices (hair, claws) as biomonitoring proxies; the analytical development of PFAS in hair and claws will be carried out by a co-supervised M2 intern
▪️ link contamination profiles to landscape data; the GIS characterisation of sampling sites (QGIS) will be handled by a second co-supervised M2 intern
▪️ coordinate both internships and integrate their results into the overall exposome analysis
▪️ take an active part in public engagement and science communication (European Researchers' Night, Fête de la Science, school visits, "Ma thèse en 180 secondes", Échosciences Pays de la Loire…)

🤝 Partners: VetAgroSup/INRAE RS2GP, BIOEPAR (Oniris/INRAE), POLLENIZ (FREDON Pays de la Loire)
