Roman Senninger

Roman Senninger is assistant professor of political science at Aarhus University, where he earned his Ph.D. with a thesis on political parties’ oversight in European Union (EU) affairs. The thesis has been awarded the Best Dissertation Prize 2019 by the European Union Studies Association (EUSA). Senninger's work has appeared in general interest and field journals including the European Journal of Political Research and European Union Politics.

At CES, Senninger will investigate the causes and consequences of policy complexity in the EU and beyond. One part of the project relies on crowdsourcing and a pairwise comparison framework to encode the complexity of EU policies. In addition, he will experimentally investigate whether policy complexity matters for ordinary citizens when they make important decisions about national politics.

Senninger is also involved in a project which investigates the European Commission’s preparation of policy initiatives, funded by the Danish Council for Independent Research. In addition, his work covers a range of topics at the intersection of national and EU politics including public responsiveness to the allocation of EU funding.
