Claudia Aradau is Professor of International Politics in the Department of War Studies and Co-chair of the Research Centre in International Relations. Claudia joined the Department in 2011, after five years of teaching and research at The Open University. Her work has explored security practices globally and has critically interrogated their political effects. She has published widely on critical security studies and critical International Relations.

Her current research focuses on the transformation of knowledge through practices of digital (in)security. Taking her earlier work on governing unknowns into a new direction, it analyses contemporary articulations of security and unknowns, particularly as mediated through data, algorithmic practices and digital devices. 

Claudia is chair of the Science, Technology and Arts in International Relations (STAIR) section of the International Studies Association (2017-2019).

She has spent a decade as associate editor and editor of Security Dialogue(until 2018). She is a member of the editorial collective of Radical Philosophy.

Research Interests

Areas of research

  • Critical security studies
  • International political sociology
  • Security practices and (non)knowledge
  • Critical methods in international relations
  • (Big) Data, algorithms and digital devices

Claudia’s current research develops three main themes. The first theme, Security’s unknowns, expands the concern with catastrophic futures in Politics of catastrophe: Genealogies of the unknownto analyse how unknowns are not just ‘tamed’ but also produced in security practices. The second project, Algorithmic Reason: The New Government of Self and Otherdevelops an analysis of the transformations that (big) data and digital devices have entailed for how social and political problems are made knowable and governable through. This project is a collaboration with Dr Tobias Blanke from the Department of Digital Humanities. Thirdly, she is developing a programme on critical methods in security studies and international relations, taking forward work published in Critical security methods: New frameworks for analysis.
