As a child I grew up within a movement of young students who moved from the cities to the outskirts to found and to experiment with several forms of shared living and working. While most of these casually interconnected “Kommunen” have faded away today due to a change of time and mood, my personal interest in forms of common or public property awoke through my studies in political sciences, social sciences and philosophy at the Heinrich-Heine-Universität Düsseldorf. Finally the so-called struggle for the high north as an example of the ongoing enclosure of the oceans raised my interest. For this reason I recently finished my master thesis “Who owns the sea? Justifications of maritime property claims”, in which I argue for a strenghtening of the CHM-principle in the maritime affairs. Right now I work as scientific assistant for ethics, political philosophy and philosophy of law at the Heinrich-Heine-Universität Düsseldorf and prepare my doctoral thesis on justifications of property rights arrangements. In the ICC-context I try to connect my personal approach to the ongoing development of an international commons movement.
