Research interests

1. Plant domestication, early agriculture (New Guinea and Island Southeast Asia) and plant exploitation (northern Australia)

My PhD research clarified that the highlands of New Guinea were a location of early agriculture and plant domestication. Since then I have continued to investigate the socio-environmental implications of early agriculture on New Guinea and in the Island Southeast Asian region. Drawing on this experience, I have become interested in the domestication of vegetatively propagated food plants in the wet tropics, especially bananas (Musa cvs). In recent years, I initiated archaeological and genetic projects seeking to clarify the long-term history of plant exploitation in northern Australia. I lead the TropArch research group in Tropical Archaeobotany at the ANU.

 2. Geoarchaeology and environmental change

I am a geoarchaeologist, namely, I draw on the disciplines of geomorphology, sedimentology and soil science to augment my understanding of archaeological sites. I have applied my geoarchaeological skills to fishpond aquaculture in Hawai`i, to early agriculture at Kuk Swamp in the highlands of New Guinea and to Pleistocene palaeosurfaces at Lake Mungo (Australia), among other sites in Australia, Mexico, South Africa and elsewhere. I am particularly interested in how human-environment interactions in the past can be used to better understand environmental problems in the present/future. I lead the Geoarchaeology Research Group (GRG) at the ANU.

3. Revising the Holocene histories of Island Southeast Asia, the New Guinea region and northern Australia

I am working with archaeologists, geneticists and linguists to re-examine: the consilience of different lines of multidisciplinary evidence for Austronesian language dispersal from Taiwan; the social significance of the Lapita phenomenon; the long-term histories of interaction between mainland Southeast Asia, Island Southeast Asia and New Guinea; and socio-environmental transformations in northern Australia.

Biography

I started out as a geographer, completing my BA (Hons) at Cambridge University (England) and MS at Penn State (USA). I then spent six years working as a consultant archaeologist, primarily in Hawai`i and England. In 1997, I came to the Australian National University to begin a PhD working with Professor Jack Golson on the emergence of agriculture at Kuk Swamp in the highlands of New Guinea. After (and partly before) being awarded my PhD in 2004, I lectured in soil science at Bournemouth University (UK, 2001-2002), in archaeology at Flinders University (Adelaide, 2002-2004), environmental change at Monash University (Melbourne, 2009-2012), archaeology at La Trobe University (Melbourne, 2013) and archaeological science at the Australian National University(Canberra, 2013-2015).

Since coming back to the ANU in July 2013, I successfully Convened the Masters of Archaeological Science program (until September 2015). During this time, I revamped the program to develop a more rigorous curriculum for training in archaeological science. From September 2015 to September 2016, I was Associate Dean (HDR) within the College of Arts and Social Sciences. Since October 2016, I have been a research only ARC Future Fellow undertaking research on plant exploitation, early cultivation and plant domestication in the wet tropics of Papua New Guinea, Island Southeast Asia and northern Australia. As part of this research, my research group is developing expertise and applying new technologies - principally microCT - to the development of archaeobotanical reference collections.
