Thomas Bruhn received a doctorate in physics from the Technical University of Berlin for his thesis on the interaction between organic molecules and semiconductor nanostructures. After research stays in Rome and Marseille, he joined the Institute for Advanced Sustainability Studies (IASS) Potsdam in 2012. Beside his research activities, Thomas is active in several nongovernmental organizations; for example, he is a member of tt30, the young think tank of the Club of Rome, and is a member of the board of directors for the Global Contract Foundation. He is also a trained moderator who regularly facilitates workshops and courses on sustainable development in adult education programs, at universities, in schools, and with the broader public. His research interests include a wide variety of issues relating to the transformation towards a sustainable way of living. In the field of natural science, this involves atmospheric science and climate engineering in particular. In addition, Thomas has an interest in transdisciplinary research beyond classical academic approaches in order to better link scientific progress and societal development. He is also interested in the development of an increased awareness of the changing role of humankind in the Earth system in light of the Anthropocene.
