Main Focus

My research uses applied geographical tools, namely palaeoenvironmental reconstruction, sedimentology and environmental history, to inform the conservation of resilient socio-ecological landscapes in a changing world. I am particularly interested in studying the long-term interactions between climate, humans and fire in tropical forest and wetland ecosystems.


Curriculum Vitae

Rebecca completed her Ph.D. in Geography at the University of Sydney, Australia in 2017. Her thesis used palaeoenvironmental techniques to examine the long-term impact of climate and fire on the resilience of south-east Asian tropical monsoon forests over thousands of years. The results of the project feed into a broader examination of how biogeographic factors and human disturbance can contribute to the long-term stability of sub-tropical forest ecosystems.

Between 2017 and 2019, Rebecca worked as a postdoctoral research fellow at the Australian National University on an Australian Research Council funded project ‘The pace and rhythm of climate: 600,000 years in biological hotspot’ under CI J. Stevenson. Her research focused on using pollen and charcoal analysis to reconstruct the floristic and fire history of Sulawesi’s lowland tropical rainforest over a million years. This work presents the longest terrestrial record of forest-fire dynamics from insular south-east Asia, and, along with complimentary research stemming from the ICDP-funded Towuti Drilling Project (lead by J. Russell) reveals the response of the Indo-Pacific-Warm-Pool to global climate change.

In 2019, Rebecca was awarded the Merewether Fellowship at the State Library of NSW (Australia). This project – ‘Conservation mapping: a case study of Sydney’s 19th century water reserves’ – marries historical and palaeoecological data to determine the actual history of remnant freshwater wetlands within Sydney’s urban core that are protected on the basis of their representing the pre-European landscape.  The results of this work contribute to a broader body of work challenging the notion that ecosystems can be protected on the basis of their “naturalness” – a common target used in the Western Hemisphere and Oceania.

Rebecca works on the ‘PANTROPOCENE’ project within the isoTROPIC Independent Research Group led by P. Roberts. She focuses on multi-proxy analysis of palaeoenvironmental records to examine the degree to which combined pre-colonial and colonial disturbance impacted the structure and composition of tropical rainforests in the bounds of the former Spanish Empire. She currently works out of the Australian National University in Canberra, Australia.
