Maitresse de conférencesCNU : SECTION 32 - CHIMIE ORGANIQUE, MINERALE, INDUSTRIELLE
Lecturer in the field of aquatic chemistry, I joined the University of Lille in 2012. My actual fields of research include drinking water treatment (disinfection by-products and organic matter characterization) and analysis of organic micropollutants with the use of passive samplers to characterize the spatio-temporal evolution of pollutions in surface and groundwaters. I hold a PhD from the University of Poitiers (France) where I focused my research on advanced oxidative processes for water treatement. I worked at Eawag (Switzerland) in collaboration with Curtin University (Australia) where I studied the formation of brominated and iodinated disinfection by-products during chlorination processes.
NOMIC project funded by the French National Research Agency (ANR JCJC 2021)
NOMIC proposes a new methodology to characterize natural organic matter (NOM) and its behavior during treatment processes. NOM is ubiquitous in aquatic environment. While nontoxic, NOM largely outweighs the reactivity of micropollutants and consumes the majority of the oxidants used during drinking water treatment. The transformation of NOM produces potentially toxic compounds in treated waters. Most of those by-products are however still unknown. Innovative tools will be applied to characterize halogen incorporation and nitrogenous reactive species in real waters. Key precursors and transformation products will be identified and a predictive modelling will be developed. An alternative methodology to evaluate the toxicity towards intestinal cells will also be developed. Finally, an on-line monitoring campaign in which a smart sampling tool will be developed will be performed on a key water resource of Lille metropolis.
