Benjamin M. Liu studies the literatures and cultures of the medieval Iberian peninsula. He is the author of Medieval Joke Poetry: The Cantigas d'Escarnho e de Mal Dizer (Harvard Studies in Comparative Literature, 2004), articles in Yearbook of Comparative and General Literature, Medieval Encounters, Bulletin of Hispanic Studies, La Corónica, and Nueva Revista de Filología Hispánica, as well as several book chapters, the most recent of which is "Ricote, Mariana y el patrón oro" in Cervantes y la economía, ed. Miguel-Ángel Galindo Martín (Cuenca: Universidad de Castilla-La Mancha, 2007). His current research project considers various economic modes of interfaith relations in early Spanish literature, examining how the circulation of money and goods among Christians, Muslims and Jews configures complex interpersonal networks among these groups. He is also developing new research on travel literature and trade in the Middle Ages.
