Mads Dahl Gjefsen is a PhD student at the Centre for Technology, Innovation and Culture at the University of Oslo. His doctoral project examines framing and expertise in policy debates on carbon dioxide capture and storage (CCS) in Norway and the United States. He focuses in particular on the role of environmental organizations as mediators of knowledge, and on their attempts to address tensions between different local, national and global concerns in relation to CCS and related environmental issues.

Before starting his PhD, Mads received his MPhil from the University of Cambridge in the field of Heritage Studies with a thesis on the construction of a Holocaust museum exhibition in Norway. He then completed an MA in the European Studies of Society, Science, and Technology program at the University of Oslo, writing his thesis on the recent attempts in STS to establish a normative theory of expertise.

Mads is affiliated with the interfaculty research initiative on environmental change and sustainable energy, MILEN, at the University of Oslo, and with the Norwegian Centre for Sustainable Energy Studies, CenSES. The Research Council of Norway funds his fellowship at the John F. Kennedy School of Government.
