Biographical details

David Guest graduated with a BScAgr in 1977 and a PhD in 1983, both from the Faculty of Agriculture. He enjoyed 20 years at the School of Botany at The University of Melbourne before returning to The University of Sydney as Professor of Horticultural Science, then Plant Pathology, in 2004. His research is driven by a fascination with the complex interactions between plants and other organisms, in particular how plants recognise and respond to potential pathogens. His research aims to discover ways to apply this knowledge to help farmers, especially in tropical countries where disease losses are highest. He has supervised 28 postgraduate research students, published over 100 books, chapters and peer-reviewed articles and been awarded over $7 million in research funding. He a frequent Keynote or Plenary speaker at national and international conferences, is a Fellow of the Australasian Plant Pathology Society and President of the Asian Association of Societies for Plant Pathology.

Research interests

Professor Guest is interested in the way plants defend themselves against pathogens at the cellular, whole plant and ecosystem levels. These questions have significance for the management of plant diseases in agriculture and horticulture. Plant diseases pose a serious threat to global food security and environmental sustainability.

His field-based research focuses on the management of Phytophthora diseases in perennial tropical crops like cocoa, coconuts, oil palm, durian and jackfruit, high value crops that are the major source of income for many smallholder farmers in countries including Papua New Guinea, Indonesia, Vietnam, the Philippines, Thailand and Colombia. His research partnerships in these countries aim to develop practical integrated crop management strategies that improve the livelihoods of rural communities, and involve multi-disciplinary teams including Public Health specialists and social scientists.

Locally, he collaborates with a range of land management authorities to develop strategies to manage dieback disease affecting native forests and bushlands, and with horticultural industries to manage diseases that affect crop yields and safety.

Teaching and supervision

Professor Guest teaches in undergraduate units at all levels, from first year Biology (BIOL1002 and AGEN1004), second year Microbiology (MICR2024), third year Plant Disease (PPAT3003) and Plant Growth and Development (PLNT3002), and fourth year Mycology (PPAT4004), Soil Biology (PPAT4005) and Agronomy (AGRO4004). At the Masters level he teaches in Crop Protection (AFNR5307).

He has supervised and co-supervised 21 PhD students and 7 Masters research students, as well as scores of honours and fourth year student projects. He currently supervises 5 PhD students.
