Current research project

DFG funded research post-IODP Cruise Expedition 385

I am currently investigating the process of magma-sediment interplay and the longevity of shallow hydrothermal systems powered by shallow off-axis sill intrusions in the Guaymas Basin, Gulf of California. These systems hold many keys to answer fundamental questions related to the role of rift magmatism in the global carbon cycle, climate change and how life may bloom during a large rifting event.

This research incorporates newly collected petrophysical data from the International Ocean Discovery Program Expedition 385 (IODP Exp. 385) to study and quantify, the multifold implications of the magma-sediment mingling process in a young rifted basin.

Other projects

  • Offshore CO2 sequestration (collaboration with GEOMAR Helmholtz Centre for Ocean Research Kiel)
  • Sill intrusion as capacitor for petroleum migration and storage (collaboration with the University of Oslo)
  • Karoo LIP volcanism – geochemistry and geochronology (collaboration with the University of Pretoria, South Africa)
  • Gas Hydrate Recycling (collaboration with GEOMAR Helmholtz Centre for Ocean Research Kiel)
