Associate Professor/Senior Lecturer in Medieval History

Research Interests

My primary research interest is in Ireland in the period 1171-1541 and, arising from that, in the wider 'English world' or 'Plantagenet empire' of which Ireland formed an integral part. Before returning to Trinity in 2013, I was a Past and Present Society Research Fellow at the Institute of Historical Research and a Lecturer in Late Medieval History at the University of East Anglia.

I am currently completing a monograph entitled England's First Colony: Power, Conflict and Colonialism in the Lordship of Ireland, 1361–1460. I have published widely on Irish and British medieval Irish history and have been commissioned to serve as editor of the forthcoming Cambridge History of Britain, vol. 2: 1100–1500.

I am Founding Director of Beyond 2022: Ireland’s Virtual Record Treasury, an all-island and international collaboration to create a virtual reality reconstruction of the Public Record Office of Ireland, and its collections, which were destroyed at the outbreak of the Irish Civil War in 1922. I am also the Academic Coordinator of the Trinity Long Room Hub's Multiannual Lecture Series entitled, 'Out of the Ashes: Collective Memory, Cultural Loss and Recovery' (2018 to 2021).

Teaching and Supervision

At undergraduate level, I coordinate Freshman Modules on ‘The Hundred Years War’ and ‘Imagining History’. For  Sophisters, my special subject 'Richard II: Kingship, Tyranny and Revolution’ explores politics and society in late-medieval Britain and Ireland. My List 2 module - 'Medieval Globetrotters: Exploration and World Conquest in the Age of the Black Death’ - examines hemispheric interactions across Eurasia during a distinctive phase of world historical development. I also offer an innovative module on the new MPhil in Medieval Studies: ‘The Middle Ages in Film: Alterity, Identity and Imagination’.

I am happy to supervise doctoral research projects on many aspects of political culture and society in late-medieval Ireland and the wider English world, particularly projects that exploit the rich records produced in the medieval English colony in Ireland. Past doctoral students have examined the legal history and parliamentary culture of later medieval Ireland and the British Isles.
