My research goals aim to improve our understanding of planetary evolution and differentiation.  In order to achieve this, I employ a wide range of geochemical and geochronological tools to a range of rock types from different tectonic and planetary environments. All research to date has encompassed the following fields of study: igneous and metamorphic petrology, geochemistry, cosmochemistry and volcanology. Current research focuses on 1) continental crust differentiation with field localities in the Central Andes of South America and the Oslo Rift, Norway; 2) magmatic evolution of continental arcs with field localities in Bolivia; 3) early evolution of the Earth-Moon system through study of Apollo basalts and lunar crustal rocks; 4) early differentiation of our Solar System through geochemical studies of chondritic material.

Possible Thesis/Dissertation Topics

  • Continental Crust growth and recycling at active margins; a crustal xenolith study of the Central Andean continental basement (potential fieldwork in Bolivia).
  • Modern evolution of the Central Andean volcanic arc; geochemistry and geochronology of Plio-Pleistocene lavas (fieldwork in Bolivia and Peru).
  • Tracing early differentiation of planetary crusts through petrology, geochemistry and geochronology: juvenile vs. recycling processes on the Moon.
  • Magma petrogenesis and crustal growth in continental rifts; granites from the Permo-Carboniferous Oslo Rift, Norway (fieldwork in Norway).
