Research interests

Biogeochemistry of the Earth's Surface Environment

  • Tracing nanoplastics in the environment: C, Pb and Ni isotopes.
  • Origin and transfer of organic matter in agricultural watersheds: the C isotopic approach.
  • Origin and transfer of iron linked to organic matter: the Fe isotopes in a wetland. 
  • Relationships between wter chemistry and weathering processes: geochemical mass balance.
