Dominique Courcot obtained a PhD at the University of Lille, in the specialty of “spectrochemistry, molecules, solids, reactivity” in 1994. In 1995, he became Assistant Professor at the University of Littoral-Côte d’Opale where he contributed to the development of research on the treatment of particulate pollutants by heterogeneous catalysis. Starting in 2003, he began a thematic conversion to study the behavior and effects of suspended particles in the atmosphere. In 2006, he was appointed University Professor and in 2010 became head of the “Chemistry and Toxicology of Atmospheric Emissions” team at UCEIV. Between 2008 and 2014, he managed the Maison de la Recherche en Environnement Industriel at ULCO. Since 2014, he has been the Director of the Environmental Chemistry and Interactions on Life Unit, UCEIV, EA 4492. His current research focuses on studying the level of exposure to airborne particles (PM10, PM2.5 and ultrafine particles) to propose atmospheric emission tracers and estimate the contributions of sources to air quality. He is also involved in research on the effects of atmospheric particles on the respiratory system, using a multidisciplinary approach involving chemists and toxicologists.
