My work at BGI

  • Collecting data on soil erosion from high-resolved lake sediment archives: new acquisitions and bibliographic searches
  • Integrating in model approaches a new paleo-database on soil erosion and C-storage for the last 200 yrs
  • Reconstructing rates of changes in global soil erosion and effects on carbon cycle

Research Interests:

  • Anthropocene
  • Lake sediments
  • Time series analysis
  • Soil erosion, surface geochemical transfers
  • Freshwater eutrophication, hypoxia (oxygen depletion)
