About

Dr Hailes joined LSE as an Assistant Professor of Law in January 2023, where he teaches all aspects of international law and arbitration, including advanced courses on energy, investment, and environmental law. He is also Academic Director of Mooting and co-coaches LSE’s team for the Philip C. Jessup International Law Moot Court Competition.

Oliver is Assistant General Editor of the ICSID Reports, previously co-Editor-in-Chief of the Cambridge International Law Journal (CILJ), and a member of the editorial boards of the Journal of International Economic Law (JIEL) and the Review of Comparative, European & International Environmental Law (RECIEL). He is also a member of the Steering Committee of the Academic Forum on Investor-State Dispute Settlement (ISDS) and an expert group on fossil fuel supply and just transition reporting to the International Union for Conservation of Nature (IUCN) World Commission on Environmental Law.

Oliver has presented his research on international arbitration and energy transition to leading universities around the world, as well as to governments (eg UK Department for Business and Trade) and international organisations (eg OPEC Fund for International Development). He has contributed to expert opinions for NGOs and to submissions before international tribunals, including the advisory proceedings on climate change before the International Court of Justice and the African Court on Human and Peoples’ Rights.

Before LSE, Oliver earned his LLM (First Class) in International Law and PhD in Law at the University of Cambridge as a Woolf Fisher Scholar, held short-term research and teaching posts, practised commercial litigation, and clerked for an appellate court. He earned his first degrees in law and politics from the University of Otago and remains enrolled as a barrister and solicitor of the High Court of New Zealand.
