Specific Interests
My research interests focus on nano-toxicology and nano-ecotoxicology. I studied Biology and received my Master’s in Analytical chemistry from the University of Toulon (France), and graduated my Ph.D. in 2017 from the French National Institute for Agronomical Research. My Ph.D. research focused on titanium dioxide nanoparticles in food, including physicochemical characterization, fate in digestive fluids and toxicity to the human gut microbiota. I then joined Dr. Minghetti’s lab in September 2018 as a post-doc researcher, to continue developing my research in nano-ecotoxicology. Here, the aim of my research is to track the chemical transformations of silver and titanium dioxide nanoparticles occurring during their uptake by the intestinal cells, as well as to identify their effects on the homeostasis of essential trace elements.
