Research Interests

Evolution and differentiation processes in the Earth and other terrestrial planets. More specifically:

  • Isotopic heterogeneities, element fractionation and chronology of events in the early solar system.
  • Element fractionation and mass transfer processes between Earth’s crust and mantle.
  • Evolution of the Precambrian surface system.
  • Cooling histories and exhumation of high-grade and high-pressure metamorphic rocks (the “early days”)
