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 important 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 am the principal editor of ‘CIRCLE: A Calendar of Irish Chancery Letters, c.1244-1509’ (https://chancery.tcd.ie/), a reconstruction of the Irish chancery rolls destroyed in the 1922 cataclysm at the Four Courts. A four-volume print edition of CIRCLE will appear with the Irish Manuscripts Commission. In September 2013, I co-founded (with Professor S. Duffy) the Trinity Medieval Ireland Series (TMIS), the first volume of which has been published as: The Geraldines and Medieval Ireland: The Making of a Myth.

Beyond 2022: Ireland’s National Memory (http://www.histories-humanities.tcd.ie/research/Beyond-2022/)
On 30 June 1922 the Treasury Room containing Ireland’s documentary heritage dating back to the thirteenth century was destroyed in a cataclysmic explosion and fire at the Four Courts. On the centenary of that blaze in 2022, this project will launch a Virtual Record Treasury that reconstructs the nation’s archives and its collective memories. In partnership with the National Archives of Ireland, the National Archives of the United Kingdom and other national and international institutions, Beyond 2022 seeks to ensure a lasting and inspirational legacy beyond the current decade of centenaries. The project has obtained major funding for a 24 month project (2017-2019) from Irish Research Council New Horizons Scheme (€219,992.50). The centrepiece of the project is a new online resource – the Virtual Record Treasury – which will provide a digital reconstruction of the Record Treasury of the Public Record Office of Ireland as it existed in 1922, on the eve of the fire. This will become not only an essential platform for academic research but also a public resource with global reach and impact among the Irish at home and abroad. The Virtual Record Treasury will provide:
-Data visualizations enabling researchers to explore the treasury of the Public Record Office and its collections
-A complete inventory of loss and survival from the 1922 fire.
-Digitizations of the surviving originals, transcripts and calendars.
-Detailed guides to the significance of those collections from the thirteenth century to the Victorian era.
-A vital hub linking replacement material held in archival repositories in Ireland and across the world.
The Irish Chancery Project (https://chancery.tcd.ie/)
This IRCHSS-funded project seeks to advance our understanding of the ‘making of Ireland’ between the high Middle Ages and the dawn of the modern era-one of the most formative periods in Ireland’s past-by publishing on the web and in print an English calendar of the rolls of the medieval Irish chancery, c. 1216-1509. The chancery was a key organ of English government in medieval Ireland. Access to its records is, however, severely restricted. The original chancery rolls suffered a series of calamities from the 13th century, culminating in 1922 with the destruction of the last 123 original rolls. A Latin calendar produced by the Irish Record Commission (1828) does not compensate for their destruction: it was poorly edited and lacks an adequate critical apparatus. Moreover, it offers no English translations and the text is printed in ‘record type’, reflecting abbreviations in the original manuscripts. This project will remedy these deficiencies by reconstructing the chancery rolls from transcripts and calendars dating from 14th-19th centuries located in Ireland and England. The outcome will be a web-based English calendar, to be followed by a multi-volume printed edition. This project will revolutionise medieval Irish studies by providing both specialists and the general public with access to an unparalleled source of information. More generally, the project will generate interest from scholars working on administrative history in a Europe-wide context and on the ‘Anglicization’ of the British Isles in Middle Ages. It will also stimulate exciting comparative work across the medieval-modern divide on the adaptation (or ‘creolisation’) of metropolitan governing practices and values in a colonial context, and on the processes of state formation and cultural exchange in the British Isles and the early modern Atlantic world.
At undergraduate level, I have taught widely on Irish, British and European history from the later Roman Empire to the Reformation. In the Freshman years, I lecture on medieval Ireland (1014-1318), Britain (1066-1215), and the Hundred Years War. I also offer a group project option on ‘Chivalry, War and Violence in the Middle Ages’ and co-ordinate the Senior Freshman module ‘Imagining History’, which offers students the opportunity to engage with history as it is presented in fiction and film.
For Sophisters, I offer List 1 special subjects on both Irish and British history, which will normally be available in alternate years: ‘Plantagenet Ireland, c.1327-99’; and ‘Richard II: Kingship, Tyranny and Revolution’. My List 2 module – ‘Medieval Globetrotters: Exploration and World Conquest in the Age of the Black Death’ – explores hemispheric interactions across Eurasia during a distinctive phase of world historical development. 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. I currently supervise doctoral students working on aspects of the legal history and parliamentary culture of later medieval Ireland and the British Isles.
