Main fields of research and expertise

Stéphane Audry got his PhD in 2003 from the University of Bordeaux, France. After two post-docs in France, he got an associate professor position at GET in Toulouse in 2006, within the M-TROPICS CZO.

His fields of expertise are:

  • Trace element cycles in aquatic systems
  • Transport and processes at the water-sediment interface
  • Early diagenesis
  • Sedimentary recording of anthropogenic pollution
  • Chemical partitioning of trace metals in suspended particles and sediment
  • Trace metal partitioning between dissolved and particulate phases
