Antonios Tzanakopoulos joined UCL in September 2011, after having taught public international law at the Universities of Oxford (2006–9) and Glasgow (2009–11). Antonios studied law in Athens, New York, and Oxford, on scholarships from NYU, the Hellenic State Scholarship Foundation, and the AHRC. During that time, Antonios also worked as a researcher for the Hellenic Ministry of Foreign Affairs in Athens (Special Legal Department) and New York (Permanent Mission to the UN), and for the UN Office in Geneva (International Law Commission). In 2011, Antonios taught as a visiting lecturer at the Université Paris X (Nanterre).

Antonios is Associate Editor for the Oxford Reports on International Law in Domestic Courts, Co-Rapporteur of the ILA Study Group on Principles on the Application of International Law by Domestic Courts, and an advocate with the Athens Bar in Greece. He has led workshops with African judges and lawyers on the application of international law by domestic courts (in Uganda and Benin), and he has worked on a number of cases before international and domestic courts and tribunals, including the International Court of Justice, EU courts, ad hoc and ICSID arbitral tribunals, and the High Court of England and Wales. His monograph, Disobeying the Security Council, was published by OUP in 2011.

Antonios’s research covers all aspects of public international law, with particular focus on the law of international responsibility, the law of international organizations, the law of treaties, the settlement of international disputes, and the relationship between international and domestic law, including the application of international law by domestic courts. Pre-prints of some of Antonios’s research papers are available from SSRN.
