My main area of expertise is the law of complicity (also known as joint criminal enterprise). I have been associated with Oxford since 2005, first as a student (BA, DPhil) and subsequently as an academic teaching Criminal Law, Tort and Contract at various colleges. Since 2017, I have been an Associate Professor at the University of Reading, School of Law, where I teach Criminal Law and Criminology. I am also an Academic Member of Libertas Chambers which (amongst other areas of law) specialises in high-profile criminal defence work.
