About me
I am a cultural and economic sociologist. I hold a BA in Sociology and an MA in Economic and Financial Sociology from Goethe University Frankfurt and a PhD from the University of Hamburg. In my dissertation, Kein Müll. Eine Soziologie vom Wert des Wertlosen (Not Waste. A Sociology of the Value of the Valueless), I combine a cultural-historical synthesis with an ethnographic investigation of upcycling as a late modern practice of value production from waste materials. My research draws on qualitative and ethnographic methods with a focus on cultural and economic sociology, sustainability, and social transformation. Before joining the DFG Humanities Centre for Advanced Studies “Futures of Sustainability” at the University of Hamburg, I taught sociology at the Chair of Society and Social Change under Sighard Neckel. I am co-author of Die Globale Finanzklasse. Business, Karriere, Kultur in Frankfurt und Sydney (Campus, 2018).
Research
My current research takes me to a remote place in southern Greenland. Just above the small settlement of Narsaq, a large geological formation cuts through the stark Arctic landscape: the Ilímaussaq Complex, one of the world’s largest deposits of heavy rare earth elements, including terbium, dysprosium and neodymium. These minerals power electric motors, wind turbines, and AI data centers—forming the material foundation of most contemporary climate technologies. Yet their extraction unfolds in a region already affected by climate change, it threatens fragile ecosystems, provokes local protests as well as global geopolitical rivalries, and thereby challenges the futures of those who inhabit it. Through a multi-sited ethnography, I follow the entangled trajectories of these rare earths from developing extraction sites to the production facilities of modern climate technologies and techno-solutionist think tanks. At the heart of my project lies a paradox: it is the very destruction of ecological habitats that opens access to the materials on which most contemporary imaginaries of climate technologies seem to depend.
