I am interested in microbial ecology and in the interactions between microbes and macrobes. For my PhD project at GEOMAR I am studying the Red Alga Gracilaria vermiculophylla, which is native to the North West Pacific and has invaded the European and North American coastal ecosystems. One of my goals is to learn if and how microbes support this organism to be a prolific ecosystem invader. At the same time I aim to address fundamental questions related to microbial community ecology. To these ends I am conducting field studies and manipulative experiments, using molecular and analytical approaches. In addition, I am interested in (aquatic) fungi and exploring uncovered marine fungal diversity.
