Specializing in public and political theology, I’m interested in the role of religions in the public square, both their problems and their potentials for the challenges that confront contemporary societies. In particular, I investigate the significance of diversity for migrant and postmigrant societies. Methodologically, my research is located at the intersection of theology with sociology, anthropology, and philosophy.

I’m the author of Elasticized Ecclesiology: The Concept of Community after Ernst Troeltsch (2017) and Terror und Theologie: Der religionstheoretische Diskurs der 9/11-Dekade (2021) as well as the co-author of The Claim to Christianity: Responding to the Far Right (2020), with Hannah Strømmen. I have (co-)edited Religion in the Public Square: Revisiting 9/11 (2023), The Spirit of Populism: Political Theologies in Polarized Times (2022), Liberal Theology Today (2019), Religion in the European Refugee Crisis (2018), Religious Experience Revisited: Expressing the Inexpressible? (2016), and Dynamics of Difference: Christianity and Alterity (2015). I also serve as editor-in-chief of the book series Political and Public Theologies: Comparisons – Coalitions – Critiques.

Currently, I’m running “Faith-Based Refugee Relief in Europe: Connecting the Empirical and the Ethical (FABRIC)”, a five-year project funded by the European Research Council. Conducted by a team of international and interdisciplinary scholars, FABRIC aims to understand and utilize the moral insights and the moral ideas that faith-based refugee relief organizations develop in practice for the cross-disciplinary debate about the ethics of forced migration in Europe.
