- Agriculture, landscape and economy;
- The formation of the Welsh March.
Andy has a particular interest in landscape archaeology and multidisciplinary research. He has led numerous research projects, including the AHRC-funded Manifestations of the Empire, which uses high-resolution pollen analysis to explore continuities and changes in environment and land-use between the Roman and early medieval periods. He is currently PI on the Leverhulme-funded Making the March: Contesting Lands in the Early Medieval Frontier and CI on Hidden Kingdoms: The South West of Britain in Late Antiquity also funded by the Leverhulme Trust. He recently co-authored the latest archaeological research framework for is early medieval Wales, and is involved in several British and European research networks, including Late Antique Hilltop Settlements in Europe (LAHIS).
