Please give 5 key-words showing your research / interest in Microbial Ecotoxicolgy:

  • Freshwater microbial communities
  • Emerging chemical contaminants (ECCs)
  • Stress biomarkers
  • Microbial OMICs
  • Nanoecotoxicology

Main kinds of contaminant(s) of interest:

  • Metals
  • Nanomaterials
  • Pharmaceuticals
  • Fungicides, pesticides and other agrochemicals
  • Microplastics
  • Contaminants from post-fire runoffs
  • Mixtures of emerging chemical contaminants

Main kinds of microorganisms of interest:

  • Freshwater fungi
  • Stream bacteria
  • Freshwater microalgae

Main kinds of ecosystems of interest:

Our ecotoxicological studies focused mainly on complex detrital lotic ecosystem with trophic interactions (plant litter microbial decomposer communities and shredder invertebrates).
Additionally, we are also interested on lentic ecosystem, focusing on the trophic interactions between microagae and filterfeeders (rotifers and daphnia).

Do you give courses on Microbial Ecotoxicology ?: NO
