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 uses the banishment of Jewish and Christian moneylenders as a lens for exploring the origins of mass expulsion in late medieval Europe. 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.
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. I am currently a Junior Fellow at the Harvard Society of Fellows. Starting January 2017, I will be joining the Department of History at Stanford University.
