Doktorandin | Planetare Geodynamik • Projekt TRR170 Late Accretion onto Terrestrial Planets
My PhD project focuses on the formation and evolution of crust on terrestrial planets with a particular interest in early Earth and Mars. With the help of numerical mantle evolution models, I investigate how interior processes affect the surface of a planet by linking mineralogical, chemical, and thermodynamic properties. With this information, a statistical overview of crustal formation and recycling mechanisms will be created and the compositional evolution of the mantle investigated.
For my research, following topics are of particular interest:
- Partition coefficient modelling depending on pressure, temperature, and melt composition
- The thermal evolution of planets
- The evolution of the mantle composition
- Different formation processes of oceanic and proto-continental crust.
