Duncan Keenan-Jones is a Lecturer in Classics and Ancient History at the University of Queensland. Before taking up the position at UQ, he held positions at the Collegium de Lyon (2017-2018), University of Glasgow (2014 - 2017) and the University of Illinois, Urbana-Champaign (2011-2014). Duncan's doctoral thesis (Macquarie University, 2011), investigated the creation and social and environmental impacts of a unique, regional Roman water supply network. Before his Masters of Arts in Ancient History (Macquarie, 2006), Duncan completed an honours degree in chemical engineering.

Duncan's research interests are focused on the intersection between Roman society, environment and technology, which he investigates using Latin and Greek texts, archaeological evidence, and geoscientific analyses of limestone deposits. His long-term research agenda is a holistic, large-scale comparison of key factors – including climatic and environmental variability, population dynamics, land use, disease, instability and governance – influencing Rome's long history, using quantitative estimates (proxies) in a humanities-based interpretative framework. He has previously excavated in Italy, Israel and Australia, and is currently part of the Glac project, investigating a late antique Imperial villa complex near ancient Sirmium (Sremska Mitrovica, Serbia).
