I work as a Research Scientist at the GFZ German Research Centre for Geosciences in Potsdam, Germany. I employ numerical methods constrained by experimental and field data to study the evolution and internal dynamics of Earth.
While the formation of present-day continental crust is largely understood, the genesis of primoridal crust (Archean TTG rocks) and the onset of plate tectonics remain enigmatic. In this project, we implemented a melting parametrisation to create primordial crust self-consistently within a global and evolutionary thermochemical mantle convection model.

In this project, we developed new tools to quantify the time-dependent correlation between continents and the subcontinental mantle temperatures and applied them to a range of incompressible and compressible thermochemical convection models. Furthermore, we investigated the possible origin of continental flood basalts.

The relative importance of plutonism and volcanism towards generating primordial continental crust is investigated with the aid of global thermochemical mantle convection models. We observed that intrusion-dominated magmatism results in hotter geotherms and the production of various Archean TTG rocks as reported from geological data.
