Professor Goldberg’s research interests include the history of medieval trade, business, and industry, definitions of regions and regional identity in Late Antiquity and the Middle Ages, epistolographic culture, and the idea and practice of law in medieval societies. She also maintains a strong interest in digital humanities, which has been methodologically important to much of her research. Her first book, Trade and Institutions in the Medieval Mediterranean: The Geniza Merchants and their Business World (Cambridge University Press, Studies in Economic History, 2012) explores the nature and geography of the medieval Islamic economy, the ways a group of merchants engaged with local and long-distance infrastructures and institutions of trade, and how notions of identity—religious, political, and geographic—affected the practices of business. Professor Goldberg has also written articles on the nature and use of merchant letters, on the economic activities of Jews under Islam, on contracts and contract enforcement regimes among medieval merchants, and on the legal persona of children in medieval canon law.
