When I moved from the south of Germany to the north of Germany in order to be close to the sea I already had in mind to study something related to marine science. I started my undergraduate studies in Biology at the University of Kiel. The marine biology courses offered at the university supported my decision to continue my education in this field. For my postgraduate studies, I moved to Hamburg and studied the Master programme “Marine Ecosystems and Fisheries Science” and I wrote my thesis about possible regime shifts in herring stocks. Now, I will do my PhD at CEES in the MARmaED project and will work with Joël Durant as my supervisor. I will study trophic interactions at the functional level based on size with data of marine organisms from the Barents Sea. This will hopefully lead to new insights into ecosystem-functioning dependent on size-structure under climate change and might help to ensure a sustainable exploitation.
