Interested in relations between Muslim and Christian societies in the medieval Mediterranean as manifested in material and visual culture. My research has focused upon the archaeology of the transition from late antiquity to early Islam in the Levant and, especially, upon the archaeology, history and art history of Sicily under Islamic and Norman rule, from the Muslims’ conquest of the island in the 9th century to the destruction of the Islamic community of Sicily by Frederick II in the 13th century.
