She is the author of numerous peer-reviewed articles on security theory, environmental security and ethics and security. She is the author of Security and the Environment: Securitisation Theory and US Environmental Security Policy (Cambridge University Press, 2010). Her second monograph entitled The Morality of Security: A Theory of Just Securitization was published by Cambridge University Press in 2019. This book offers a new way of approaching ethics and security by bringing together insights from moral philosophy via the just war tradition, and Security Studies via securitization theory. This book develops principles of just securitization concerned exclusively with when securitization (i.e. the use of emergency politics whereby putative threats are addressed using exceptional means) is morally permissible. Dr Floyd’s a follow-up monograph theorising whether, and if so what kind of, actors can have a moral obligation to securitize, to what referent objects is called The Duty to secure: From just to mandatory securitization. This book is in press and will be published by Cambridge University Press in early 2024.
