Rolf Lidskog, Professor in Sociology at Örebro University in Sweden, will be the new visiting researcher at the working group Political Sociology (Straßheim). Rolf Lidskog’s research interests include environmental policy and politics at the international and national levels, especially the role of expertise in environmental governance. A central issue in this research is how actors perceive, evaluate and manage risks, where there are conflicting views on what is the most suitable way to manage them. To answer this question, he has studied a variety of environmental areas: climate change, biodiversity loss, air pollution policy, nuclear waste management and hazardous waste management. Rolf will give a lecture at the ISOS colloquium on 23 April on 'Environmental expertise for social transformation: meaning, roles, and expectations‘.
