Research themes:

  • Mechanisms influencing the speciationthe bioavailability and the toxicity metals and metalloids
  • Interaction between soil, plants and micro-organisms at the rhizosphere
  • Transfer of contaminants inorganic (metals, nanoparticles) in the soil-plant system
  • Phyto-extraction metals and metalloids, in particular rare earths
  • Extraction of critical metals from secondary resources through bio-inspired techniques


The complexity of the environment studied requires interdisciplinary approaches: physical chemistry, soil science, plant physiology, microbiology, and the use of different tools to characterise the mechanisms, such as the study of speciation by X-ray absorption spectroscopy or imaging.
