Research topics

  • Aquatic microbial communities : phylogenetic diversity, spatio-temporal dynamics, metabolic activity, and resistance/resilience in human-impacted environments
  • Symbioses between microbes and marine invertebrates from Atlantic, Mediterranean and Antarctic coastal environments
  • Antagonistic relationships among microbes : ecological fundament and biotechnological potential
  • Biogeography, eco-physiology, genomics and biotechnological applications of hard-to-cultivate microorganisms (focus on the phylum Acidobacteria)
