I am a Lecturer (Assistant Professor) in Public Law and Legal Theory at the University of Surrey School of Law, a member of the Surrey Centre for Law and Philosophy, and a Research Associate of the University of Oxford Programme for the Foundations of Law and Constitutional Government.

Previously, I taught Constitutional Law, Jurisprudence, European Union Law and Roman Law at the University of Oxford. I was also a Visiting Scholar at the University of Melbourne.

I published in the Oxford Journal of Legal Studies, the Law Quarterly Review, Public Law, Notre Dame Law Review Online and in several edited collections. I also blog (e.g., at the UK Constitutional Law Blog and at I·CONnect ). (For details see my Publications page.)

I specialise in public law (constitutional and administrative law) and in legal theory (philosophy of law). My doctoral research focuses on unlawful (or unconstitutional) ways of changing constitutions. In that project, I elucidate and develop HLA Hart’s account of secondary rules – and especially – of the rule of recognition.

As a former computer programmer, I am interested in applications of technology in law (Legal Tech), both from practical and philosophical perspectives. Currently, I am developing a research project on machine learning for predictive analytics in law.

I am also pursuing projects on Brexit (disentangling UK and European Union law, constitutional consequences) and on the role of fundamental rights and principles in statutory interpretation.
