Research Interests

I am very interested in the interactions of algae with their environment. During my master thesis (University of Bonn, Alfred-Wegener-Institute, Bremerhaven and AWIPEV Arctic Research Base on Svalbard) I worked on the impact of global warming and interspecific competition on Arctic kelps. Therefore, I observed the development of kelp spores under rising temperature, changing light conditions and increased sedimentation and studied the impact of global change on kelp-grazer interactions.

Now in my PhD project my focus lies on biotic interactions. I am investigating the interaction of Saccharina latissima with filamentous endophytic brown algae - in particular  Laminarionema elsbetiae - by combining different approaches like barcoding, physiological growth experiments, qPCR and transcriptomics.
