My main research interests are in Middle English literature, especially devotional texts and prose writing of all types, and in the manuscript contexts in which medieval texts survive. I have recently completed a monograph on how Tudor readers engaged with later medieval texts (forthcoming with Cambridge University Press), and have previously worked on medieval scribal production (John Shirley: Book Production and the Noble Household in Fifteenth-Century England). I have published a volume for the Index of Middle English Prose (Handlist XIX: Manuscripts in the University Library, Cambridge, Dd-Oo), and have co-edited several collections of essays including Design and Distribution of Late Medieval Manuscripts in England (with Linne Mooney), and Insular Books: Vernacular Manuscript Miscellanies in Late Medieval Britain (with Raluca Radulescu). I am also interested in textual criticism and have produced scholarly editions for the Early English Text Society and for Middle English Texts. I have recently co-edited a collection of essays, Editing and Interpreting Middle English Texts (with Raluca Radulescu) which is forthcoming with Brepols. I am a General Editor of The Mediaeval Journal and of the Middle English Texts series published by Winter (Heidelberg).
