Dr. Kara Susan Gaston is an Associate Professor of English at the University of Toronto Scarborough. Her research interests include late medieval English and Italian literature, Chaucer, reception of the classics, form and formalisms, vernacular translation, gloss and commentary, and medieval astronomy. Her first book, Reading Chaucer in Time: Literary Formation in England and Italy, uses source study to reassess the relation between formation and form in Chaucer's poetry. Her current research focuses on literature and astronomy, including the textbooks of Sacrobosco and Al-Farghani and the poetry of Aratus, Virgil, Ovid, Lucan, Dante, and Chaucer. It explores what it means to think about the cosmos in literary terms and vice versa.
