Visiting Lecturer, Borns Jewish Studies Program, 2017-18

I am a social and economic historian of medieval Europe, with a particular focus on the Western Mediterranean. My research explores how gender and religious identity shaped the legal, social, and economic options available to medieval women. I am especially interested in medieval Iberia, which was home to thriving Jewish, Christian, and Muslim communities.

In my current book project, I compare how Jewish and Christian women negotiated economic life in medieval Catalonia, with a particular focus on three cities—Barcelona, Girona, and Vic—between 1250 and 1350. This project stems from my doctoral dissertation, “Gender, Religious Difference, and the Notarial Economy in Medieval Catalonia, 1250-1350.” I employ an expanded definition of women’s work, which encompasses the management of resources as well as wage labor and the artisanal crafts, to argue that families relied on women’s labor to ensure the solvency of the household. However, Jewish women played a much more marginal role, due to marriage and inheritance practices that limited women’s authority over financial resources.

My next research project will explore how Jews in medieval Iberia used the notaries, Christian public officials and legal professionals, to record contracts related to inheritance, marriage, and divorce, as well as the limits of these intersections between Jewish and Christian legal culture. Both projects address how and why the spheres of gender and the family proved essential for Jewish communities actively working to maintain boundaries between themselves and their Christian neighbors.
