Justiina Dahl is a postdoctoral researcher at the Division of History of Science, Technology and Environment at KTH Royal Institute of Technology in Stockholm. Her research interests lie at the intersection of environmental studies, international relations and STS. The kinds of problems Dahl tackles in her work include: Do technical and scientific experts hold similar or different position as other forms of expertise in global governance?
