Geraldine works on the literature of medieval Iberia and is interested in the formation of Spain’s collective identity during the medieval and early modern periods (thirteenth to seventeenth centuries). Her research explores the tensions involved in this process as seen through the lens of early literary texts, and focusses on the dark side and the margins, specifically on treachery, wrongdoing, and illegitimacy. She has published on epic poetry (the Cantar de Mio Cid as well as other less familiar epic poems), clerical poetry (mester de clerecía), the popular ballad tradition, and historiography. Geraldine has also written and published on Golden-Age drama, and continues to work across the medieval and early modern periods. Her most recent book is entitled Narratives of the Islamic Conquest from Medieval Spain (Palgrave Macmillan 2015) and she has also recently written a book chapter on the lost epic narrative of the Jura de Santa Gadea. She is presently working on a new monograph exploring literary representations of illegitimacy in Spanish literature from the medieval and early modern periods.
