My research has focussed on the farm, food and bioenergy policies of the European Union (EU), particularly its common agricultural policy (CAP), and the process of trade liberalisation in these products under the auspices of the WTO (World Trade Organization); and more recently Brexit. I have written, lectured and advised extensively on these topics. A list of recent publications can be found here.

I have undertaken work for the FAO (Food and Agriculture Organization of the United Nations), the Commonwealth Secretariat, ICTSD (the International Centre for Trade and Sustainable Development), IFPRI (the International Food Policy Research Institute), CEPS (the Centre for European Policy Studies in Brussels), the European Parliament, and various UK government departments including Defra and Dfid. I have advised Select Committees in both Houses of the UK parliament.

I have given public evidence on Brexit to various parliamentary committees (see also Videos link at the top of this page). Transcripts can be read here: External Affairs and Additional Legislation Committee of the National Assembly of Wales (19 September 2016); House of Lords EU Energy and Environment Sub-Committee (25 January 2017); Commonwealth of Australia Joint Standing Committee on Foreign Affairs, Defence and Trade (7 August 2017).

I am a Past President (2009-10) of the Agricultural Economics Society.

In September and October 2017 I was a Visiting Fellow in the ANU Centre for European Studies at The Australian National University, Canberra.
