My research interests cover a wide variety of topics in public law, especially in terms of their international, European and comparative perspectives. In this respect, my research focuses on democracy and the rule of law, fundamental and human rights, and constitutional adjudication as well as comparative constitutional and administrative law, particularly concerning questions of methodology and current challenges. I regularly participate in interdisciplinary research projects at the interface between law and language, law and political science, law and sociology, and law and technology.
