My research interests as a research Engineer are focused on the adaptation and development of models that describe the bio-physical interactions between flows, biology and chemistry processes involved in biogenic elements and contaminants transfers in rivers at different time and space scale. More specifically, i aim to integrate by modeling the particular role of interfaces zones (ex: water/land, water/sediment) and specific buffer zones (ex: wetlands) in the dynamic of element transfer at large scale.
