Sarah Percy arrived at UQ from the University of Western Australia in 2016. Prior to her appointment at UWA, Sarah was University Lecturer and Tutorial Fellow in International Relations at the University of Oxford (Merton College). At Oxford, Sarah was on the steering committee of the Oxford Programme on the Changing Character of War. Sarah did her M.Phil and D.Phil as a Commonwealth Scholar at Balliol College, Oxford.
Sarah has three main research areas. She has had a long-standing interest in unconventional combatants, and has published widely on mercenaries, private military companies, and pirates. Sarah is interested in issues of maritime security generally, including piracy and counter-piracy, maritime crime, and the role of navies as security actors. She also conducts research at the nexus between international relations and international law, and is interested in how and why the use of force is regulated, and the relationship between norms and international law.
Sarah's research projects have had considerable impact outside academia. Sarah has presented her research on mercenaries and private military companies at the United Nations; at policy-oriented events at Princeton University and New York University; and at the Royal United Services Institute (London) and the International Institute for Strategic Studies (London).
Sarah's research on piracy was featured in the production notes for the film "Captain Phillips", directed by Paul Greengrass and starring Tom Hanks. She has presented this research to the Royal Navy and at DFAT's Counter-Piracy Conference. Sarah has also presented on maritime security and strategy to the Royal Australian Navy, and at the RAN's Sea Power Conference in 2014, and to the Federal Court of Australia's Maritime and Admiralty Law group in 2015. Sarah is a non-resident fellow of the Royal Australian Navy's Sea Power Centre.
Sarah is an experienced media commentator. Her writing has appeared in the Guardian, USA Today, The Conversation, and The Lowy Interpreter. She has appeared on radio in the United States (National Public Radio) and in Australia (Radio National, multiple programs including Rear Vision and The World Today) and on Sky News.
