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.

 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. I am particularly interested in how human-environment interactions in the past can be used to better understand environmental problems in the present/future.

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 am the new convenor of the Graduate Certificate and Masters of Archaeological Science programs at the Australia National University (from July 2013).

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), in archaeology at Flinders University (Adelaide), environmental change at Monash University (Melbourne), and archaeology at La Trobe University (Melbourne).
