Research interests

  • Geochemistry of stable (B, Ca, Li, Mg) and radiogenic (Sr) isotopes
  • Mass spectrometry
  • Water-rock interaction at low and high temperatures
  • Isotope fractionation during water-rock interaction
  • Chemical mass balances: continental vs. hydrothermal fluxes into the ocean
  • reconstruction of climatic and environmental information using coldwater corals
