Research interests

  • Behaviour of moderately chalcophile/ siderophile elements during mantle melting
  • Behaviour of the extended high-field strength elements (Nb, Ta, Zr, Hf, W, Mo) in subduction zones
  • Application of stable metal/metalloid isotopes in geo- and cosmochemistry.
  • Development and optimization of analytical techniques for MC-ICPMS measurements
  • Volcanism in post-collisional tectonic settings (Bulgaria), in active subduction zones (Santorini, Indonesia) and intraplate settings (Eifel, Siebengebirge)
  • Origin and age of the supergiant Olympic Dam Cu-U-Au-Ag deposit in S-Australia
