My research interests are in the fields of public and administrative law. More specifically, I am interested in the following topics and areas of administrative law:
- Administrative justice, in particular administrative tribunals and adjudication
- Administrative rule-making
- Law, administrative organizations, and institutional and constitutional design
- Law and public policy implementation
- Administrative accountability
- Asylum and immigration law
I have a particular interest in immigration and asylum as a substantive area of law. In 2001, I was seconded to the Home Office to undertake empirical research into immigration appeals and the use of judicial review by asylum applicants. I have received external funding from the British Academy and the Nuffield Foundation to support empirical research into asylum appeals. In 2007-2010, I undertook an empirical research project into the procedure and determination of asylum appeals by the Asylum and Immigration Tribunal. This project was funded by the Nuffield Foundation and the book "Administrative Justice and Asylum Appeals" was published by Hart Publishing in 2011. This book was awarded the first place in the Society of Legal Scholar's Peter Birks Prize for Outstanding Legal Scholarship, 2011. I have also co-authored an advanced textbook entitled "Public Law" with Dr Mark Elliott (University of Cambridge), the 3rd edition of which was published by Oxford University Press in 2017.
