Planet Earth is a dynamic system in constant evolution. Most of the dynamics of our planet are controlled by Earth’s mantle. The mass transfer between Earth’s mantle, crust and atmosphere is controlled by the production of new oceanic crust in the spreading centers, the recycling of material into the mantle and the segregation of the continental crust at convergent margins. Additional mass transfer from deeper reservoirs are represented by isolated sources of magmatism and heat fed by deep mantle plumes.


My group research mantle melting processes, the development and evolution of different geochemical reservoirs of Planet Earth (especially the mantle and the crust), the deep geochemical cycles (from ocean crust production and subduction to the deep recycling) and mantle sources (peridotite vs. pyroxenite). My goal is to contribute to the understanding of how Planet Earth works internally and how this affect the surface. My approach to study these processes is from a geochemical perspective
