Gouverneur research is centred on late-stage fluorination to benefit pharmaceutical drug development, medicine and imaging. Her laboratory also aims at changing the way fluorochemicals are produced and manufactured at scale. This programme focuses on novel fluorine chemistry bypassing e.g. the requirement to produce and transport dangerous fluorochemicals such as hydrogen fluoride and F2, and new strategies to upcycle fluorochemical waste including PFAS in the spirit of a circular fluorine chemistry economy.
