My research and teaching experience has been in human behavioural ecology, rock art studies, palaeoecology, zooarchaeology, stone artefact analysis and hunter-gatherer archaeology. I have carried out field work and research in most Australian states and, internationally in England, China, Jordan and France over the last 30 years. The time period that I study is from the Palaeolithic to the Holocene periods, from about 1 million years ago up to the historic period. I have advised the Tasmanian forest industry, ICOMOS, the World Heritage Centre and the Tasmanian Aboriginal Lands and Sea Council on cultural heritage matters for over 20 years. I work closely with the Queensland Wet Tropics, Aboriginal communities and Environmental Protection agencies, northeast Queensland on Indigenous cultural heritage management.
