Prof Doyle is a leading expert on comparative constitutional law and theory, with a particular focus on foundational questions of constitutionalism: how are constitutions made? How do constitutions relate to a particular people and territory, particularly in contested cases of secession and territorial conflict? How are constitutions changed? In 2018, he published a monograph, 'The Constitution of Ireland: A Contextual Analysis' for Hart's series on Constitutional Systems of the World. This book provides the first analysis, richly informed by comparative study, of how the Irish Constitution as a whole operates in practice. Prof Doyle is currently collaborating with Prof Rachael Walsh on a number of papers related to Ireland's experiment with citizens' assemblies and how these may inform new approaches to constitutional amendment. Developing his previously published work on territory (International Journal of Constitutional Law, German Law Journal), Prof Doyle is developing a new research project on Constitutional Space. This will explore both how constitutions help to create and maintain territory and how constitutions respond to territorial contestation, whether in the form of secession, federalism, and conflicting territorial claims. Other recently published work explores various aspects of constitutional change, including informal change, constraints on amendment powers, interest-group politics, constitutional transitions, deliberative democracy, typologies of constitutional change, and populism.
