I am a chemist specialized in organic geochemistry and working as permanent researcher at CNRS (UMR 6118 Geosciences Rennes), France. My research focus on how the molecular composition of natural and anthropogenic organic matter can be translated into valuable information in term of origin and dynamic. My current work involves (i) the mechanisms of solubilization of dissolved organic matter along the the soil-stream continuum, (ii) the source of particulate organic matter exported during extreme events and (iii) the fate of colloidal plastics along the continent-ocean continuum.
