- Human environmental relationships in the tropical north of Australia. With colleagues from Macquarie University, ANU, University of Waikato and QUT I am investigating the coastal archaeology of the Weipa region in collaboration with Rio Tinto Alcan. We are investigating the large number of shell mounds in the Weipa region studying their construction, chronology and composition. Funded by an Australian Research Council Linkage Grant 2011-2013.
- Early agriculture in Egypt with colleagues from UCLA and Rijksuniversiteit. I am interested in how mobile people adapted to variable past environments. The Egyptian research deals with people who were just developing agriculture, adapting to fluctuating desert environments in the mid-Holocene but continuing to pursue a mobile lifestyle. Funded by a Marsden Grant 2012-2014.
- The Western New South Wales Archaeological Project (WNSWAP) with Associate Professor Patricia Fanning, Macquarie University, investigating Holocene surface archaeology from a geoarchaeological perspective. We are particularly interested in issues of chronology and the interpretation of long-term human behaviour as well as stone artefact technology.
- I have a long term interest in the study of stone artefacts in general with a particular interest in Australia.
- I direct a research group with interests in the historic archaeology of Taranaki, New Zealand. In 2004 we excavated the site of Oropuriri, a 19th century Māori village as a contract for Transit NZ.
