Dr Morgan’s research focuses on state power particularly in the arena of national security, counter-terrorism, surveillance, and intelligence. She analyses the intersection between public law, political theory, socio-legal thinking and critical consideration of liberalism. She has an enduring interest in state secrecy, the UK security services, the regulation of investigatory measures and the responses of liberal theory to contemporary political practices and is currently writing a monograph on the topic. She is also working on the conception of transparency in the Five Eyes intelligence sharing partnership.
Her most recent publications explore secrecy in the courts and analyse extremism as a superficially attractive but normatively hollow legal concept. 'Cloistered justice: The opposing trends of barricade and respective secrecy' (2026) advances a conceptualisation of secrecy used in court and argues that a friction is developing in the justifications for secrecy applied in courts. 'Guilded tombs do worms enfold: 'Pyrite concepts', Terrorism, and Extremism in a Pluralist UK' (2026) authored with Dr Alan Greene argues that vague legal concepts that rely on extensive executive discretion damages the pluralist basis of contemporary democracy. Dr Morgan has previous co-authored Accountability and Review in the Counter-Terrorist State with Professor Fiona de Londras and Dr Jessie Blackbourn, (Policy/ Bristol University Press, 2019) considered how the counter-terrorist state has become a normalised and permanent aspect in the UK and what a meaningful commitment to accountability should look like in that context. Utilising empirical analysis of high-level interviews and in-depth examination of current laws and accountability practices, the book draws a detailed map of counter-terrorism review in the UK, analysing where it succeeds and fails.
