Recent work has been published in journals such as Political Communication, the Proceedings of the National Academy of Sciences (PNAS), the International Journal of Press/Politics and West European Politics. I am leading collaborative projects on digital media and populism funded by the Volkswagen Foundation and on negative campaigning funded by the German Research Foundation (DFG).
