I’m Professor of Law at University College London, Director of the Centre on International Courts and Tribunals in the Faculty, and a key member of staff in the Centre for Law and the Environment. I am a Barrister at Matrix Chambers and a writer.

Everything that I do – teaching, research, writing, litigating cases – revolves around my great passion, which is international law, the settlement of international disputes (including arbitration), and environmental and natural resources law.
