Research Interests

Sedimentary geochemistry, marine systems, biogeochemical cycles

Research Program

My current research includes

  • early diagenesis in modern marine sediments and its impact on primary depositional signals
  • subsurface metal cycling and its implication for the (ultra-) deep biosphere
  • investigation and application of paleoproxies with emphasize on redox-sensitive trace metals
