Claudia Aradau is Professor of International Politics in the Department of War Studies and Principal Investigator of the Consolidator Grant Security Flows (‘Enacting border security in the digital age: Political worlds of data forms, flows and frictions’), funded by the European Research Council (2019-2024).

Her research has explored the implications of security practices globally. As more and more problems and people become constituted as objects and subjects of security, she has inquired into the effects this has for democratic politics and critique.

Her current research focuses on how digital technologies reconfigure security and surveillance practices, as well as the relations between security, democracy and critique.

Claudia spent a decade as associate editor and editor of Security Dialogue (until 2018). She is a member of the editorial collective of Radical Philosophy and member of the editorial boards of Security Dialogue and International Political Sociology.

Research interests

  • Critical security studies
  • Security practices in the digital age
  • International political sociology
  • Critical methods in international relations

Her current research develops three main areas. Firstly, the ERC project Security Flows examines the epistemic, political and ethical implications of the datafication of border security. The project is situated at the intersection of critical approaches to borders and security, Science and Technology Studies and data studies.

Secondly, a book project co-authored with Tobias Blanke, entitled Algorithmic Reason: The New Government of Self and Other, analyses the ways in which big data and algorithmic practices have reconfigured how social and political problems are made knowable and governable.

Thirdly, the international collaborative project GUARDINT (‘Oversight and intelligence networks: Who guards the guardians?’) examines oversight practices in a threefold way: as a democratic mechanism, as socio-technical networks, and as an emerging transnational practice. This project inquires into how the relation between security and democracy is recast when digital surveillance has become both increasingly normalised and intangible.


Claudia has designed modules on ‘Critical Security Studies’ (BA3) and ‘Risk and Uncertainty in Global Politics’ (MA).
