Research Area

My research focuses on trace metals (TM) at the various interfaces of the ocean including estuaries, coasts, atmosphere, hydrothermal sources and upwellings. My aim is to understand the TM reactivity and, more specifically, their interaction with natural organic matter, marine organisms and marine ecosystems. In parallel, I sometimes develop electrochemical methods.
