Research Biography

Mathilde Delaval joined CMA in July 2021 as a research scientist. She earned her PhD degree in Toxicology in 2015 at the University Paris Diderot, France. During her studies, she investigated the adverse effects of nanoparticles on the human airways using in vitro lung models. Her research activities are focused on the evaluation of air pollutants (e.g. nanoparticles, ambient particles, electronic cigarette aerosols) on human health, with a specialization in pulmonary toxicology and in vitro-based new approach methodologies (NAMs).
