School of Law
I joined the School of Law as Lecturer in September 2020. Before coming to Sheffield, I taught and worked toward my PhD at the London School of Economics and Political Science. In 2017/18 I was Judicial Fellow to His Excellency Judge Giorgio Gaja at the International Court of Justice in the Hague.
I have taught public international law and EU law at the LSE, public international law at the University of Oxford, EU law at the University of Buckingham, and public law and international law of the sea at the Australian National University.
I am admitted as a Lawyer in the Supreme Court of the Australian Capital Territory and previously worked in the Australian federal court system. I have been involved in numerous projects with the British Institute of International and Comparative Law, the British Institute of International Affairs (Chatham House), and Oxford Pro Bono Publico.

- Research interests
As a generalist public international lawyer, my interests and expertise span a range of topics, including sources of international law, treaty interpretation, international dispute settlement, environmental law, and the law of the sea.
My research currently centres on topics in international economic law, particularly international trade law and international law concerning foreign investment. I am particularly interested in the capacity of existing legal frameworks to facilitate social and environmental justice.
My doctoral project addressed approaches to rule ascertainment and interpretation in international investment arbitration, States’ regulatory powers, and the reconceptualization of investment law as a form of ‘international public law’.
My Areas of Research Supervision include:
- Sources of international law and rule ascertainment
- Interpretation in international law
- State jurisdiction and immunities
- International legal personality and State responsibility
- International dispute settlement
- International investment law
- International trade law
- International law of the sea
- International environmental law

- Teaching interests
International law is a fascinating, challenging, and incredibly diverse field.
My teaching strategy is built around student engagement, active participation, and problem-based learning. I encourage my students to understand how the law operates in theory, and how it is used and operates in practice, and equip them with the knowledge and tools to subject the law and legal processes to critical reflection.
I often draw on my research and my practical experience in international dispute settlement when designing activities — encouraging my students to assess the causes of, and find solutions for, contemporary challenges in international affairs.
I am committed to helping to ensure the School remains an inclusive and supportive learning environment and to do my upmost to support my students during their time at Sheffield.
