Présentation

Originally from the Jura region, I studied biology and population dynamics at the University of Burgundy, before completing a PhD in 2023 at the veterinary school "VetAgro Sup", in collaboration with the French Office for Biodiversity and the Laboratory of Biometry and Evolutionary Biology. My doctoral research focused on the environmental and phenotypic determinants of parasitic infestation heterogeneity in roe deer (Capreolus capreolus), highlighting on the still little explored links between essential mineral elements and parasitism in a large wild mammal. Wishing to remain in the field of wildlife health, I oriented my postdoctoral work toward ecotoxicology. In 2024, at the Centre for Biological Studies of Chizé, I investigated the effects of pesticides on the physiology and microbiota of farmland birds such as the Montagu’s harrier (Circus pygargus) and the grey partridge (Perdix perdix). In response to the growing issue of chemical pollutants, I continued my research in 2025 at the Chrono-environment laboratory, where I am currently working on the SPACEMOD and COMICS projects, among others, which focuse on the effects of multi-contamination (pesticides, trace metal elements) on food webs and the health of small mammals, in particular the digestive microbiota, at both individual and population levels.
