Contact Dr Gleider I Hernández (email at


Gleider I Hernández is Senior Lecturer in Public International Law at Durham Law School and a founding Deputy Director of the new Durham Global Policy Institute. For 2014-2015, he is the Director of Undergraduate Admissions for the Law School, and Convenor of the Law and Global Justice at Durham research cluster, which he also convened in its previous incarnation as Law and Conflict at Durham (2011-2013).

Gleider took a D.Phil from Wadham College, Oxford in 2010. Previously, he read for an LL.M (cum laude) at Leiden University (the Netherlands) and for BCL and LL.B degrees at McGill University (Canada). His doctoral thesis was published in May 2014 by the Oxford University Press, as a monograph entitled The International Court of Justice and the Judicial Function. It was shortlisted for the Peter Birks Prize for Outstanding Legal Scholarship by the Society of Legal Scholars.

Prior to arriving in Durham, he served as Associate Legal Officer at the International Court of Justice (2007-2010), acting from 2008-2010 as Law Clerk to Vice-President Peter Tomka and Judge Bruno Simma. At the Law Faculty of the University of Oxford, Gleider worked as a Graduate Teaching Assistant, leading tutorials in Public International Law (2005-2007). Also at Oxford, he was appointed as Teaching Fellow at the Environmental Change Institute (2006-2007), where he lectured in international environmental law; as Senior Editor of the Oxford University Commonwealth Law Journal (2006-2007); and as Convenor of the Public International Law Discussion Group (2005-2006). Gleider has also practised as a barrister and solicitor, in public and administrative law, at the law firm Fasken Martineau DuMoulin LLP (Montreal, Canada), until 2004.

Gleider's research interests lie within the general area of public international law, and particularly relate to international legal theory (nature and sources of international law), international dispute settlement, and the law and practice of international institutions. He also has an interest in how specialised areas of international law (eg international criminal law, international environmental law, international investment law, and the law of armed conflict) interact with general international law.

Gleider is a Member of the Academic Review Board of the Cambridge Journal of International and Comparative Law, the Co-ordinating Committee of the International Legal Theory Group of the European Society of International Law, and General Editor of the online rouce Oxford International Courts of General Jurisdiction (Oxford Scholarship Online). Gleider is also a Member of the International Expert Group drafting the 2nd edition of the Tallinn Manual on the International Law applicable to Cyber Warfare (Cambridge University Press, 2016).

Gleider will, from October 2015, take up a two-year Early Career Fellowship from the Arts & Humanities Research Council, on a project entitled 'Constructing Authority in International Law'. He also currently holds an appointment as Junior Faculty with the Harvard Institute for Global Law and Policy. Previously, he has also been a Visiting Fellow at the Faculty of Law, McGill University (August-October 2013), and the Amsterdam Centre for International Law, Universiteit van Amsterdam (March-June 2014). 

Gleider is fully fluent in English, French and Spanish, and is competent in Dutch.
