I joined the University of Leeds as Professor of Business Law in January 2016 after 14 years at the University of East Anglia, which I joined as a lecturer in law in September 2001 after seven years of undergraduate and postgraduate study at Oxford University. I was appointed to a personal Chair at UEA in November 2011. My doctoral thesis, entitled "Mistakes of Law", focused on the historical development of the mistake of law bar, its eventual abolition in 1998, and the impact of that change on the future of the law of restitution. I was Distinguished Visiting Fellow at the TC Beirne School of Law, University of Queensland in the Spring of 2014.

My main research interests are in unjust enrichment and its normative justifications. I examine the law of unjust enrichment from a comparative perspective, looking in particular art mixed jurisdictions such as Scotland and South Africa, but also German law. I am currently writing a monograph on the scope and structure of unjust enrichment law for Hart Bloomsbury, for whom I also wrote a textbook, The Principles of Personal Property Law. Within personal property I am particularly interested in the law of secured transactions and I am a member of the Secured Transactions Law Reform Project in the UK.
