“How to use data science to link air quality and health?”
After high school, I wanted to work with the tools we use every day, so what could be better than computer science. I enrolled in an engineer school specializing in computer science, and because I wanted to work more with mathematics, I specialized in modeling, applied mathematics, and artificial intelligence. To deepen my knowledge, I completed a parallel Master's degree in Data Science, taught in English, at Université Clermont Auvergne.
“Microplastics at home: turning evidence into prevention”
A consistent thread throughout my professional path has been my commitment to addressing questions of public interest. My master's degree in analytical chemistry led me to explore several research domains, including forensic analysis, water and food quality. I then took my first steps into air-quality research by studying the composition of bitumen fumes inhaled by workers during road-paving operations. Beyond the laboratory, I am actively involved in science dissemination. I won an award at the regional edition of My Thesis in 180 seconds, spoke at the Science Festival, and co-organize the Pint of Science festival.
