My PhD project is part of the project CARBOSTORE (Carbon Storage in German Coastal Seas). Within the project, my research focusses on the coupling of trace metals with benthic nitrification and denitrification. The results will be linked to remineralization and burial processes in marine sediments and will help to estimate the impact of (anthropogenic) trace metal inputs on the nitrogen and carbon cycle. Within the CARBOSTORE project, I will measure trace metal concentrations, nutrient concentrations and N-isotope ratios in water, sediment and pore water samples from the open North Sea and the Wadden Sea. The results will be complemented by incubation experiments.

My research interests in the field of environmental and analytical chemistry cover the following areas:

  • Seawater and sediment analysis
  • Trace metal analysis
  • Analysis of nitrogen compounds
