Stuart Needham specialised in metalwork in his early career and has since diversified to cover many aspects of the Chalcolithic and Bronze Age of north-west Europe, involving themes such as deposition practices, metal circulation systems, periodisation, life- and refuse-cycles of material culture, exchange systems, maritime interactions, and alluvial archaeology. Further publications have emanated from excavations at Runnymede Bridge and Ringlemere. A curator at the British Museum for thirty years before becoming an independent researcher, he co-founded the Bronze Age Forum in 1999 and delivered the Rhind lectures for the Society of Antiquaries of Scotland in 2011. He was recently Research Director of the People of the Heath project investigating Early Bronze Age barrows in the Rother Valley of East Hampshire and West Sussex. Catriona Gibson has worked extensively in both commercial and academic archaeology. Her research interests include exploring evidence for connectivity and mobility during later prehistory, the Beaker/EBA periods in western Europe, and forging stronger bridges between developer-led and academic archaeology. She is one of the authors of Grave Goods: Objects and Death in Later Prehistoric Britain. Peter Chowne is a Senior Honorary Fellow of the Department of Archaeology, University of York.
