Gavin Melville is a Senior Research Scientist (Biometrics) and works as a consulting biometrician at the Trangie Agricultural Research Centre. His activities include design of agricultural experiments, data analysis, survey design and statistical research.
Gavin joined NSW Agriculture (NSW DPI) in 1991 as a biometrician and undertakes research into sampling methodology, including issues related to forestry surveys, surveys of wildlife and plant ecology sampling. He has over 30 years of statistical experience including time with the Australian Bureau of Statistics, Commonwealth Department of Health and Australian Institute of Health and Welfare. He has written over 130 scientific papers, 40 per cent of which are in peer-reviewed publications.
