My research focuses on Critical Security/Critical Military Studies, discourse theory, German and U.S. foreign policy, and International Political Sociology. In my PhD project I used insights from the political discourse theory of the “Essex School” to explain changes in the German security discourse, most notably the expansion of military operations outside the NATO area (so-called out-of-area operations) after the end of the Cold War. That study examined over 25 years of parliamentary debates. In more recent research, I have turned my attention also to the visual aspects of the representation of military operations, in particular in the context of social media.

More recently, together with Dirk Nabers and partners from SciencesPo Paris, Queen Mary, University of London, King’s College London and the International Christian University in Tokyo, I have started an initiative for a project examining the nexus between populism and global order. We are currently in the process of acquiring funding for that project.


1) The German Politics of Military Force: The Discursive Production of Out-of-Area Operations

In my Ph.D. project, which I am currently developing into a book, I analyzed the discursive production of what I call the German “out of area consensus” that emerged in the German Bundestag after unification. The empirical basis is a discourse analysis of German parliamentary debates from 1987 to 2013.

2) Exploring the Visual Representation of Out-of-Area Operations on Social Media

Together with David Shim (University of Groningen), I have also begun to analyze how out-of-area operations are represented visually. A first output of the project has recently been published in Global Discourse. In the article we explore the (gendered) visual representation of the ISAF operation on the German armed forces’ official Facebook page. Currently, we work on a second paper on military recruiting. Specifically, we look at the YouTube web series Die Rekruten (The Recruits), which is produced by the German armed forces.

I am also a member of the DFG-funded research network Visuality and Global Politics.

3) Populism and Global Order

The project is concerned with the nexus between populism and global order. Although populism as such has received significant research interest across the social sciences, its international dimensions remain largely unexplored. The project sets out to close this gap in the literature. At the same time, the project strives to contribute also to International Relations (IR) scholarship, which has so far neglected populism as a research topic. However, if there is indeed a “global rise of populism” (Moffitt 2016) – and this seems to be the case –, this will unavoidably have (and de facto already has) a significant impact on a broad range of topics commonly considered to be among IR’s core concerns, including foreign policy, international conflict and cooperation, rule and resistance in IR, and regional and global order(s). As such, doing IR will become ever more difficult in the future if populism is not taken into account. Based on a cross-national structured, focused comparison of different national cases, the proposed project plans (1) to provide systematic knowledge on how different populism(s) and global order are related and (2) to develop a middle-range theory of populism and global order.

Non-state Actors and Foreign Policy

In this small project, Rainer Baumann (University of Duisburg-Essen) and I tentatively explored two questions: (1) to what extent non-state actors are involved in states’s foreign policies and (2) if theoretical approaches to the study of foreign policy are equipped to address non-state actor involvement.
