Research Interests

My academic history lies in public international law, with a focus on international economic/trade law.  Since completing my PhD, I have become particularly interested in EU law as a model for trade and cooperation.  These days, I am something of an EU law omnivore; I tend to latch onto particular Court of Justice or EU legislative developments and consider the implications (both EU-wide and within Member States) of these developments.

At the moment, I am working on the following projects:

- Organising healthcare for a potentially migrant citizenry: what (if anything) can the EU learn from the US?  (Project funded by the British Academy and Leverhulme Trust.)

- Performing Identities (funded by the ESRC) - alongside Colin Murray, Aoife O'Donoghue and Ben Warwick.

In November 2015, I was interviewed about the legal consequences of a 'Brexit' by BBC Radio 4's Law in Action; the interview can be downloaded/listened to here.  In 2017, I gave evidence on the implications of Brexit for trade and the border in Northern Ireland to the Northern Ireland Affairs Committee and the Commons International Trade Committee. In 2018, the Lords Select Committee on the European Union invited me to give evidence on the future UK-EU relationship. Also in 2018, the Lords Constitution Committee invited me to give evidence on the role of the European Parliament in scrutinising EU treaties.

Postgraduate Supervision

Note: I am currently not able to take on more PhD students.  In general, I would be interested in supervising any postgraduate research projects on EU law, particularly those that take a comparative approach to evaluating the effects of EU measures on Member States in a variety of social and economic fields.
