I studied psychology at the University of Freiburg and wrote my thesis on contradictions and conflicts in commons projects. The notion of the commons caught my attention a couple of years ago. The concept struck me because it can grasp a variety of aspects crucial to the understanding of the crises of our time. I am involved in commons projects such as community supported agriculture, transition towns and self organized education. My interests are in the theory and practice of societal transformation, critical psychology, degrowth, coordination and communication in commons projects and the maker movement.
