His research interests lie at the intersection of deliberative democracy, democratic innovations, social norms, and climate and environmental governance. In his current research projects, Janosch is concerned with the question whether, or under which conditions, deliberative mini-publics, such as citizens’ assemblies, can enable more ambitious climate action at the national level, while limiting risks of policy backlashes and societal polarization.
