BA, MPhil, PhD (Cambridge)

Academic background

After completing my PhD on ninth-century Francia at the University of Cambridge, I worked in the Department of Coins and Medals at the Fitzwilliam Museum, Cambridge as a research associate on the Medieval European Coinage project and the Anglo-Saxon Coins in Norway project. This triggered my enduring fascination with coins and their potential to illuminate the past. Subsequently I have held fixed-term lectureships in medieval history, including at the University of St Andrews; Birkbeck, University of London; and at the University of Oxford, most recently at St Catherine's College and Trinity College. 

Undergraduate teaching

I teach the medieval British and European and World History papers, c. 300–1300; the Mongols Optional Subject; Approaches to History: Archaeology; and Disciplines of History.

Research interests

My research explores the experience of participating in economic and political networks in the early middle ages. I use written and coinage evidence to explore questions including economic practices, concepts of value and regional boundaries in Francia, the Viking world and England c. 750–1100. I am currently completing my monograph on the Carolingian emperor Lothar I (795–855), Lothar I and the Remaking of Francia, 843–855, which draws in particular on the royal charters. I also work on the movement of coins within Anglo-Saxon England, Scandinavia and the Baltic as evidence for trade links and cultural transfers. I am increasingly engaged by themes in global history in my research and teaching.
