I am the Yeoh Professor of Politics, Philosophy & Law at the Dickson Poon School of Law, King’s College London, where I also direct the Yeoh Tiong Lay Centre for Politics, Philosophy & Law. I work in legal, moral and political philosophy. I have written on political authority, just war, human rights, and philosophy of the criminal law. I am currently interested in moral agency, with a focus on the notions of autonomy, responsibility and meaning in life. In 2020, I took up a two year Leverhulme Trust Research Fellowship to work on a book project on manipulation.

I have held visiting appointments at the Australian National University, the philosophy departments at the University of Virginia and at the University of Arizona, the Murphy Institute (Tulane), the Centre for Legal Theory at the National University of Singapore and the Nathanson Centre for Transnational Human Rights, Crime & Security (York). 

I am an affiliated researcher at the Stockholm Centre for the Ethics of War & Peace and part of an AHRC-funded project on Protecting Cultural Heritage in War.

I am also the Honorary Secretary of the Society for Applied Philosophy and one of the editors of Law & Philosphy and Criminal Law & Philosophy.
