Research Interest

I focus on the 'Sea Surface Microlayer' (SML), which describes the surface film at the boundary layer at the oceans surface. A variety of organic substances accumulate in the SML, which are formed by both primary primary and secondary production and are subject to continuous changes due to abiotic processes such as solar radiation. The SML influences the exchange of energy and mass between the atmosphere and the ocean and thus directly influences gas exchange and aerosol formation. The electrochemical analysis of surface-active substances as well as the analysis of sugars and amino acids are at the core of my work.
