Tracie is currently involved with the Beef Genetics unit of the NSW Department of Primary Industries, but has also worked in other sections (mainly livestock) within the Department since 1990.
Previous work within the Department included, site manager for the Sheep CRC Information Nucleus Flock at Trangie, genetic analysis and extension of research for the Advanced Breeding Services unit and daily management of sheep research projects.
Tracie recently completed a Research Masters in animal breeding (Genetic analyses of flystrike in sheep) and also works in the Cropping Systems unit.
