Research Interest

Understanding natural systems as highly complex and self-regulating networks has been my motivation throughout academic education. My undergraduate studies in Biology led to the question how ecosystems, in particular their imprint within time and space, are connected to Climate and Earth Science. I therefore enrolled for my M.Sc. degree at Kiel University in cooperation with GEOMAR Helmholtz Centre for Ocean Research focusing on Marine Biogeochemistry. I graduated with a thesis about the ocean boundary layer in which marine organisms and substances become enriched, the so called 'Sea Surface Microlayer' (SML), and potentially influence mass and energy transfer across the ocean-atmosphere interface. I focus on the analysis of dissolved and particulate carbohydrate and amino acids as products of fresh production and degradation and the electrochemical measurement of surface-active substances. I aim to bridge SML research to marine gas and particle atmospheric chemistry.
