My research activities focus on complementary issues related to metallic trace elements, their environmental fate, reactivity, speciation, source apportionment using stable isotopes, toxicity on aquatic organism and exposure to humans.

I cover analytical developments in environmental (bio)geochemistry and application of geochemical tracers and metal stable isotopes to large scale (Gironde and Scheldt watersheds) and point source systems related to urban/domestic acticvities (wastewater treatment plants), metal processing plants and ore-forming environments.
The purpose is to quantify mixing relationships, investigate transfer processes, speciation and reactivity for legacy (Pb, Cd, As, Cu, Zn,...)  and emerging (Ag, Pt) trace metals. ​

Recent topics covers human health risk assesment and human biomonitoring related to contaminated soils, including the design of soils guideline values using toxicokinetic and probablilistic models for Pb, Cd, As and PFAS.
