Brent Miles is an Associate Professor of medieval Celtic languages and literatures at the Centre for Medieval Studies and St. Michael’s College. He researches principally the vernacular literatures of medieval Ireland and Wales, though he has a strong second interest in Hiberno- and Anglo-Latin. The bulk of his published work to date has concerned the study of classical pagan poetry and mythology in medieval Ireland and the relationship of this classical learning to the native corpus of heroic narrative in Irish. A monograph on this subject, Heroic Saga and Classical Epic in Medieval Ireland, was published by Boydell & Brewer in 2011, and 2020 saw the second book in this project, Don Tres Troí: The Middle Irish History of the Third Troy, published by the Irish Text Society. More recently, in 2023 Brent completed his An Introduction to Middle Welsh: A Learner's Grammar of the Medieval Language and Reader (published as an open source resource on TSpace). Current projects include a study of treatises on biblical kingship in Irish and Hiberno-Latin.

Before joining the University of Toronto Brent was a Visiting Professor and Senior Lecturer in the Department of Celtic Languages and Literatures at the Adam Mickiewicz University in Poznan, Poland. Prior to taking up that position, he held a Post-Doctoral Fellowship at University College, Cork, and conducted research as a visiting scholar at the Dublin Institute for Advanced Studies. He received his PhD from the Centre for Medieval Studies.
