Dr David Walton has extensive experience in horticulture in both a practical and academic sense. Practical experience comes from a career in horticulture before enrolling at university. Subsequently he completed a PhD based on postharvest issues of macadamia nuts. David also has a keen interest in sustainable agriculture, environmental management and native vegetation.
Postdoctoral research has involved the ecology and breeding system of Eucalyptus argophloia (Chinchilla White Gum); adapting and refining techniques for postharvest processing of the tropical nut Canarium indicum to benefit farmers in the South Pacific (Papua New Guinea, Vanuatu and the Solomons); and investigating the cause of brown centres in macadamia kernels. Present research involves the development of a Canarium nut industry in the South Pacific One of Dr Walton’s main tasks now is to convert team research in to peer-reviewed scientific papers.
