My primary academic research interest is the history and culture of the Mediterranean world. The bulk of my scholarly publications have focused on the crusading movement, the medieval republic of Venice, and the interaction between the cultures of Latin Christendom, the Byzantine Empire, and the Muslim Middle East. These are topics of enduring and timely interest.
