Daniel Power studied at Selwyn College, Cambridge, from 1987, and held a research fellowship at Trinity Hall, Cambridge, from 1993. In 1996 he was appointed to a lectureship in the Department of History at the University of Sheffield, where he was promoted to Senior Lecturer in 2005 and Reader in 2007. He took up the post of Professor of Medieval History at Swansea University in September 2007. He is currently the Head of the Department of History and Classics.

Professor Power’s research concerns the history of France and the British Isles in the Central Middle Ages (especially the Anglo-Norman realm, the Angevin Empire, and Capetian France) and medieval frontier societies. His publications include The Norman Frontier in the Twelfth and Early Thirteenth Centuries (Cambridge: Cambridge University Press, 2004), and he has edited The Central Middle Ages (Short Oxford History of Europe (Oxford: Oxford University Press, 2006) and (with Naomi Standen) Frontiers in Question: Eurasian Borderlands 700-1700 (Basingstoke: Macmillan Press, 1999). His recent publications include a study of participants in the Albigensian Crusade, but they mainly concern the Anglo-Norman aristocracy in the 13th century, after the end of the Anglo-Norman realm in 1204, for which he established the database The ‘Lands of the Normans’ in England (1204-44); he is also preparing a critical edition of the 400 charters of the Hommet family, constables of Normandy in the 12th and 13th centuries.

Professor Power is the Director of MEMO, Swansea University’s Centre for Medieval and Early Modern Research. He is a Member of the Société de l'Histoire de France, and a Fellow of the Society of Antiquaries (of London) and the Royal Historical Society.
