Miss Tegan Harrison

Graduate Tutor

School of Law and Politics


I am a full-time PhD research student in the School of Law and Politics. My doctoral thesis is on outer space security in the United Nations. It explores the securitization of space in the context of the prevention of an arms race in outer space.

I am also the committee secretary for the Defence Research Network (DRN).


I work as a tutor on the 'International Politics in the Nuclear Age' third-year module and the 'Introduction to Globalisation' first-year module.

Academic Background:

BSc Sociology (2017-2020) Loughborough University.

MA Security (2020-2021) Loughborough University.


My research looks at the securitization of outer space through the case of the United Nations agenda item, 'the prevention of an arms race in outer space' (PAROS). In this context, the project focuses on the framing of space security since the 1980s and across various PAROS initiatives in the UN First Committee and Conference on Disarmament.

I am also interested in the intersection of space and nuclear security issues. Specifially I explore the use of satellites for arms control verification and monitoring and the impact of open-source intelligence for this purpose.


I am PGR tutor for two modules at Cardiff University:

  • International Politics in the Nuclear Age - third-year module.
  • Introduction to Globalisation - first-year module
