My research revolves around externalities. These arise when decentralized markets fail, for example in the context of environmental pollution or congestion, and call for an intervention by the public sector. A particular focus of my research lies on the functioning of cap-and-trade markets for emissions and their interaction with electricity and fuel markets, and on transport pricing. I am furthermore interested in questions related to fiscal federalism, behavioral public economics and health economics.

I am a member of the environmental and resource economics chapter of the German Economics Association (AURÖ) and the CESifo Research Network and from 2015 to 2020 part of the Swiss Competence Center for Research in Energy, Society and Transition (CREST).

I am member of the Research Network Sustainable Future.
