My research focuses on questions of:

  • mantle geodynamics
  • volcanology and
  • geochronology


and includes studies on:

  • long-term isotopic signatures in the mantle
  • Tethyan and Rheic Ocean crust chemistry
  • mantle convection, using 3D spherical numerical models
  • intraplate magmatism, especially across Central Asia
  • using geochemistry as a tool to understand emplacement of pyroclastic density currents
  • improving our understanding of Ar-dating
