Bio


I am a historian of western Europe and the Mediterranean, primarily during the high and late Middle Ages. Much of my research tries to understand how law and society interact with each other, especially where legal norms conflict with social practices. Another strand of my research explores the history of economic life and economic thought, especially medieval debates over usury and moneylending. I have also written on the circulation of goods, people, and ideas in the medieval Mediterranean.

My current book project (Conflicts of Interest: Jews, Christian Moneylenders, and the Rise of Mass Expulsion in Medieval Europe) uses the banishment of Jewish and Christian moneylenders to explore the rise of mass expulsion as a widespread practice in the later Middle Ages. A second ongoing project examines the ways in which medieval canon law was adapted, reinterpreted, or resisted in local contexts in the thirteenth and fourteenth centuries. The latter builds on Corpus Synodalium, a searchable full-text database of late medieval local ecclesiastical legislation that I have been developing since 2016, with assistance from colleagues around the world.

Born and raised in western Canada, I did my undergraduate and doctoral work at Harvard University, earning an MPhil in Medieval History from the University of Cambridge along the way. Before coming to Stanford, I was a Junior Fellow at the Harvard Society of Fellows.
