Dr. Thilo Wiertz

University of Freiburg

Member of the Young Academy for Sustainability Research
October 2021 - September 2024


Thilo Wiertz is a Human Geographer and post-doctoral researcher at the Institute of Environmental Social Sciences and Geography, University of Freiburg. He obtained his PhD in 2015 from the University of Heidelberg where, as member of an interdisciplinary research group at the Marsilius Kolleg, he studied the Global Governance of Climate Engineering. From 2015 until 2017, he worked as a project scientist at the Institute for Advanced Sustainability Studies (IASS) in Potsdam, facilitating the engagement between science and society around topics such as Climate Engineering and Arctic Sustainability. His research on Climate Engineering explores how computer simulations have changed global perspectives on the environment, and how they inspire visions of technological climate control. Drawing heavily on assemblage theory and the philosophy of Gilles Deleuze, his recent research crosses boundaries between political geography, discourse studies and science and technology studies to interrogate the ‘digital geopolitics’ of far-right activism, biopolitics of migration and borders, and geopolitical dimensions of mobile energy storage systems.
