I’m a philosopher, builder, and communicator.

As a philosopher, I have worked on themes like culture, identity, and perception. My interests, though, extend also to (the philosophy of) public philosophy, the history of modern thought, ethics, and political philosophy. The various intellectual styles in philosophy crossed my way abroad. Experiences as a research assistant in Princeton, as a visiting professor in Brazil and China, and as a Humboldt-Fellow in Chicago shaped my views tremendously.

As a builder, I enjoy to create projects on both well-known and less known themes, problems, and challenges of our time. To make an old dream come true, I have founded the denkwerkstatt grenzenlos, a non-profit organization in Berlin, Germany. This work was accompanied by writing a book on public philosophy.

As a communicator, I enjoy working with people with different backgrounds in various ways. Being the director of the denkwerkstatt grenzenlos, I find great pleasure in forming teams for different projects and in making team work an enriching part of life. My experiences as a teacher at universities and as head of many projects surely help me to give my best.
