Research areas

Tom's wider research interests lie in parliamentary scrutiny of the executive and the legislative process. He is particularly interested in the relationship between executives and legislatures and the innovative ways in which parliaments seek to boost their influence with the executive. His interest in this area of legislative studies stems from the way governments within Westminster-style democracies can dominate legislatures. He received a PhD in Political Science from Newcastle University in June 2019, funded by the Economic and Social Research Council. His thesis examined post-legislative scrutiny in the UK Parliament and was the first systematic study of this type of parliamentary scrutiny. The thesis explored where and how often post-legislative scrutiny had taken place, what the processes of scrutiny involved, the extent to which committee recommendations were being accepted and how both Houses of the UK Parliament differ in their undertaking of it.

He has presented this research at European Consortium for Political Research and Political Studies Association Annual Conferences and at an ECPR summer school. He has also presented research at more specialist events, including events with the Westminster Foundation for Democracy.

His commitment to engagement and impact has been demonstrated through having given oral and written evidence to the Scottish Parliament’s Public Audit and Post-legislative Scrutiny Committee, as well as giving written evidence to both the House of Commons and House of Lords Liaison Committees for their respective inquiries into their committee systems. His drive to disseminate my research to both academic and practitioner communities has assisted him in building both national and international research networks.

Tom also has a burgeoning interest in teaching and learning research having assisted with two research projects during his time at Newcastle University, one focusing on student attendance and engagement and the other on study skills.
