Denis holds a BA (2001) in Archaeology and History and an MA (2002) in Landscape Archaeology from University College Dublin. In 2014 he was awarded a PhD (2014) from Monash University (Melbourne) for his doctoral research, ‘Changing Places: An Archaeological Study of Manilikarr Country in Western Arnhem Land’, a study which focused on the historical emergence of Aboriginal freshwater identities. Between his post-graduate studies Denis worked as a professional archaeologist for nearly 10 years, covering a wide array of research topics. He was granted full Irish archaeological licence eligibility in 2006 and since that date has acted as senior archaeologist on a range of projects. Denis’ current research interests lie in the sub-disciplines of landscape archaeology, community archaeology, Indigenous Australian archaeology/archaeology of rock art, human-environment interactions and the historical emergence of identity. He has published locally, nationally and internationally on these topics. He is also an adjunct with Australia National University (ANU Researcher). Denis joined the Irish Archaeology Field School as partner in 2014, and company director in 2016.
