Keywords: anthropized catchments, headwaters, nutrient, carbon, suspended solids, water and solute transit times, biogeochemistry



Current research topic

My research topics are hydrology and biogeochemistry. I am interested in understanding the processes that determine the water quality of streams and rivers, especially in the context of agricultural environments. I use diverse monitoring and modelling approaches to characterize the transfer, transit times and reaction processes of water and some major chemical elements, mainly nutrients (N, P) and C.

I focus on small headwater catchments (10 ha - 100 km2) to medium-scale catchments (ca. 1000 km2).

I am involved in several observation platforms for research. In particular, I am scientific coordinator of a research observatory on agricultural catchments: the AgrHyS Observatory.

Current projects
  • Ecological Restoration of the Sélune River: Dynamics of water, sediments and dissolved chemical elements in the Sélune River before, during and after dam removal (2014-2021)
  • Biogeochemical processes of intermittents and ephemeral rivers and streams in temperate and oceanic context (2022-2025). Supervision of the Ph.D. thesis conducted by Andres Casanova and programme OBTAINER funded by Region Bretagne. 
  • eLTER PLUS: Advanced community project for long-term ecosystem research in Europe (2020-2025)
  • STRANGE: Ecosystem services supplied by aquatic ecosystems to adjacent agricultural environments at different scales.
