I am currently working at the Toxicology and Biometrology Department, INRS. My research interests lie in the areas of nanotoxicology and risks associated with mixed-exposures. My main scientific contributions are related to atmospheres generation (including nanoparticles aerosols) and characterization for rodent inhalation exposure purposes and to the development of analytical methods for the measurement of substances of interest in biological media. Thus, I contribute to in vivo studies who address nanomaterials pulmonary toxicity, metabolic interactions between chemicals and exposure to noise and ototoxic agents.
