Professor Hamerow is Professor of Early Medieval Archaeology in the School of Archaeology and the Faculty of History, and is a Fellow of St Cross College. Her research focuses on the archaeology of rural communities in early medieval Europe. She is particularly interested in how the establishment of kingdoms, monasteries, markets and towns affected farming, farmers and the early medieval countryside.
Her research also explores the emergence of the earliest Anglo-Saxon kingdoms, in particular the kingdom of Wessex, whose origins lie in the Upper Thames Valley. This has led to a multi-disciplinary project (The Origins of Wessex) investigating the British contribution to West Saxon identity and how the leading families of the Gewisse (a group who later came to be known as the West Saxons) used material culture and the landscape itself to strengthen their position.
