I am an archaeologist and architectural historian specializing in the study of medieval sites and their representation. I am currently Professor of the History of Art and Architecture, and Professor of Archaeology. I have excavated in England, France and Israel, and I currently direct the MonArch excavation and research project in northern France at the Augustinian abbey of Saint-Jean-des-Vignes in Soissons, the Carthusian house at Bourgfontaine and the Cistercian monastery at Notre-Dame d'Ourscamp.
