2004, Université Libre de Bruxelles, Belgium.


  • Projects:
    • scientific coordinator of the SCAR-Marine Biodiversity Information Network (SCAR-MarBIN)
  • Field of expertise:
    Distribution, fluxes and impacts of anthropogenic contaminants (heavy metals, PCBs, PAHs, PCDD/Fs) on marine benthic ecosystems. Main experimental models : Bacteria, Echinodermata, Amphipoda.
