I joined the School as a Lecturer in Law in September 2019. My research interests include all aspects of Public International Law though, at present, I am particularly focussed on the international law of the sea and on jurisprudential questions concerning the international legal order.

I am also an Academic Fellow of the Honourable Society of the Middle Temple (starting October 2021).

Prior to joining Cardiff University, I completed my doctoral studies at the University of Bristol under the supervision of Professor Sir Malcolm D. Evans KCMG OBE and Professor Eirik Bjorge. My doctoral thesis was nominated for the prize of "outstanding excellence in a doctoral dissertation in social sciences".

I have a research profile complete with a number of articles, chapters and books, published, accepted to be published and in development. I am an active participant at academic conferences in my field.

I teach the following modules:

    • Public International Law (Module Leader)
    • Equity and Trusts
    • Undergraduate Dissertation

I have previously taught Jurisprudence to undergraduates and the Law of the Use of Force to postgraduate taught students. 

I am accredited as a Fellow of the Higher Education Academy (FHEA).

My primary research field is Public International Law. My current work engages two key sub-disciplines of Public International Law: (1) the international law of the sea, and (2) jurisprudential questions concerning public international law.

I am currently working on a co-authored monograph with Professor Sir Malcolm D Evans for Edward Elgar Publishing on the International Law of Islands (expected publication early 2023). I am also leading a research project examing the legal consequences of illegality in international law.


I am currently co-supervisor of a PGR research student. I welcome research proposals in areas relating to my research interests.
