Research interests

  • Physics of (past) climate
  • Oceanography and Paleoceanography
  • Marine Geochemistry
  • U and Nd Isotopes

I'm interested in the physics of our climate system and its changes during past and future. My research is focused on the ocean circulation, which plays a key role in transitions between different climate states. Using a multi-collector ICPMS, I investigate different tracer systems, such as neodymium and uranium isotopes in seawater and environmental archives, to gain new insights into the marine geochemistry and water mass dynamics.
