I work across a number of fields and periods, including: medieval literature (English, Latin, French); literary theory from ancient to modern; the history of rhetoric; the reception of classical traditions in medieval and early modern Europe; intellectuals, learning, and literacy in medieval Europe; history of the emotions. Usually my teaching combines my interests in antiquity and the Middle Ages--or how the Middle Ages understood antiquity. I recently published The Oxford History of Classical Reception in English Literature vol. 1, 800-1558 (2016). Other recent work includes essays on commentary and gloss, and on Aristotle's Rhetoric in medieval England. My current project is a book on emotion and the history of rhetoric. I am also interested in representations of the intellectual in pre-modern Europe, from late antique rhetorical culture to late medieval university cultures and heretical communities. Other work includes Medieval Grammar and Rhetoric: Language Arts and Literary Theory AD 300-1475, co-authored with Ineke Sluiter;and The Cambridge Companion to Allegory, co-edited with Peter Struck. I was a founding editor of the annual New Medieval Literatures ). I am General Editor, with Peter Mack (Warwick), of the Cambridge History of Rhetoric, a series in five volumes to be published in 2023. I am also co-editor, with Jill Ross, of Toronto Studies in Medieval and Early Modern Rhetoric, a new book series from Pontifical Institute of Mediaeval Studies. In fall, 2010, I was a fellow at the Institute for Advanced Studies in Jerusalem, working in the research group Encountering Scripture, on medieval Christian, Jewish, and Islamic approaches to scriptural exegesis. In Spring 2013 I was a Fellow at Penn's Center for Advanced Judaic Studies for a seminar year on innovations in the thirteenth century. In Spring 2020 I was a Visiting Fellow at the Warburg Institute in London.
