Biography
Megan is Chair in Public International Law at the European University Institute. Her research spans public international law, its theory and history.
Her research on contemporary international law has focused on treaty-making and sources, self-determination, and international criminal law. She has also explored the workings of international institutions, with an emphasis on transparency; public law and constitutional values; and the use of languages of public law in global governance. Her historical work has examined the development of the international legal order over the nineteenth and twentieth centuries, again with an orientation to foundational areas like the law of treaties, diplomatic relations, peace, war and statehood.
Moving between the contemporary and historical has animated an interest in methodological interactions between law and other disciplines. She explores how each approaches texts and material traces; how different scales (national, imperial, global) and strands (intellectual, social, cultural) of historical scholarship might engage differently with law; and how lawyers might meet scholars from other disciplines on the terrain of the present or recent past.
Her current work carries these interests into an exploration of how interstate cooperation in migration and transnational crime is evolving through both legal and other forms. In 2026–27 she will teach seminars on (Legal) Archives of the Present, and on Crime, Statecraft and the Imagination of the Global.
Megan has degrees in law and history from the University of Melbourne, an LLM (Legal Theory) (2010) and J.S.D. from New York University School of Law (2016). She was Lecturer and Associate Professor at University College London (2019–26), and Junior Research Fellow in the History of International Law at King’s College Cambridge / Lauterpacht Centre for International Law (2015–19).
