My Research


I investigate reservoir interactions and their timing in different spheres of the Earth’s system including atmosphere, biosphere, hydrosphere and the Earth’s crust. In particular during the last years I have developed a strong interest in the associations among geodynamic setting, petrogenesis of magmas and the formation of porphyry-type deposits at convergent margins. I also work on technical developments in the field of lead isotope analyses of whole rocks and on ore minerals dating using Pb-Pb stepwise leaching and Re-Os techniques. Recently I have started to work on the application of unconventional stable isotopes (Cl, Cu, Zn, Fe) to the petrogenesis of arc magmas and to track environmental changes.

Current Research Directions

  • Relationships between arc magma chemistry, geodynamics and genesis of porphyry-type deposits.
  • Rates of magmatic processes and their influence on the genesis of prophyry-type deposits.
  • Petrogenesis of andesites and implications for crustal growth.
  • Cu and Zn isotope compositions of magmatic rocks and volcanic fumaroles.
  • Various projects in collaboration with researchers of the Section of Earth and Environmental Sciences of Geneva, University of Padova and UNIL on petrogenesis of magmatic rocks and Sr isotope stratigraphy.
