About Me

Research Scientist, Head Molecular Environmental Geochemistry


Research Interests

  • Speciation and fate of trace elements in natural and engineered environments
  • Nanoparticle formation and its impact on trace element dynamics
  • Influence of variable redox conditions on trace element behavior
  • Bioavailability and mobility of contaminants and nutrients
  • Element speciation by synchrotron-based X-ray absorption spectroscopy

Main Research Projects

  • Sorption of thallium to illite and birnessite and its impact on the solubility of thallium in soils
  • Iron(III) precipitates formed by iron(II) oxidation in water: Structure, reactivity and impact on arsenic
  • Characterization of the redox properties of iron minerals by combined electrochemical and spectroscopic analyses (PI Thomas Hofstetter, Eawag)
  • Behaviour of silver nanoparticles in the urban water cycle (PI Ralf Kaegi, Eawag)
