Julie is a postdoctoral researcher, working with Dr Richard Bailey and Professor David Thomas in the School of Geography and the Environment. She is also a stipendiary lecturer at Brasenose College.
Julie was awarded her PhD from Aberystwyth University in 2012. Her research focused on the luminescence dating of river systems in Pakistan and relating changing fluvial activity to the collapse of the Harappan civilisation.
Her research interests include palaeoenvironmental reconstruction, civilisation collapse and response to climatic variability, human dispersal in African and Arabia and developing the use of optically stimulated luminescence (OSL) dating.
Julie's current research is focused on a number of key areas:
- Understanding the relationship between society and environment, with a particular focus on the use of OSL dating to develop chronologies of landscape change that can be used to assess the role of environmental variability in the collapse and transformation of ancient civilisations.
- Further exploration of the role of climatic variability and environmental change on the Harappan Civilisation in Pakistan and India.
- Exploring the timing and migration of modern humans from Africa into Arabia and Asia, using OSL dating to better constrain periods of aridity and humidity and to provide dates for environmental change at key archaeological sites.
- Investigating the physical properties of luminescence signals in saturation, with the aim of improving the precision and accuracy of equivalent dose and age determinations, as well as working towards extending the dateable age range of using the OSL signal from quartz.
- Developing an improved understanding of the physics of the luminescence signal.
