He has also worked as Research Agronomist at Wagga Wagga in southern NSW investigating a range of issues including grazing management of dual purpose wheats, wheat agronomy and precision agriculture.
Guy returned to the northern grains region in 2007 to work on several projects in the northern grains region. He currently leads the Northern Barley Agronomy project working closely with collaborators at QDPI&F and with similar projects in southern and western Australia. Guy also coordinates the NSW DPI Northern Barley Evaluation group evaluating breeding lines from Barley Breeding Australia.
