For 47 years I have worked as a biological anthropologist with Indigenous Australians. My research has investigated social, cultural and environmental influences on population genetic diversity in Aboriginal Australia. Situated since 1971 in north-east Arnhem Land, this research has widened to include medical anthropology, nutritional health, ethnobiology and the Yolngu management of their natural and cultural landscapes. Over the past 15 years my work has increasingly focused on community development in the Donydji homeland, with the help of Vietnam Veteran volunteers and philanthropic funding, especially through the Rotary Club of Melbourne, which presented me with its Vocational Service Award. I have also worked as a consultant on a number of issues, ranging from Indigenous heritage, land rights and health to identification of skeletal remains. These consultancies have included the WA and VIC State Governments, the Australian Heritage Commission, the Northern Land Council and the Aboriginal Sacred Sites Authority in Darwin. In 1998 I was awarded Membership of the Order of Australia (AM) in recognition of my research in biological anthropology and community work with Donydji and other Yolngu homelands.
