I am an early-stage postdoc at the IOW and my current research focuses on coastal nitrogen cycling and the anthropogenic effect on coastal ecosystem functioning. During my PhD in the COCOA project, I studied pelagic nitrification, its regulation and role in coastal N-turnover. I specifically focused on river plumes and the bottom boundary layer as potential hot-spots of nitrification. To understand the role of biogeochemical transformations in complex coastal ecosystems it is inevitable to do on interdisciplinary research. Thus, I would like to broaden my scientific expertise towards the combination of sediment biogeochemistry, microbiology (composition, structure, activity, function of microbes) and physical oceanography (hydrodynamics of coastal systems).

Research expertise

  • Coastal nitrogen cycling, in particular nitrogen retention processes like nitrification
  • Stable nitrogen isotopes (natural abundances, tracer incubations)
  • Nutrient exchange across the sediment-water-interface (chamber lander deployments)
  • Dissolved organic nitrogen (DON) along salinity gradients
  • Anthropogenic impact on ecosystems and biogeochemical processes
  • Interdisciplinary research
  • experience in planning, realization and data handling of cruises and lab-experiments
