I am the Dame Louise Richardson Chair in Global Security at the Blavatnik School of Government of the University of Oxford. I am also a Fellow at Trinity College and Co-Director of the Oxford Institute for Ethics, Law, and Armed Conflict (ELAC). My research concerns the role of law and morality in international relations, specifically in war. I focus on three strands of work. I am a 2021 Philip Leverhulme Prize Winner.
