Biography
John is a plant pathologist and research leader specialising mainly in pathogens of vegetable crops. He is involved in a range of different projects from basic/strategic to applied, funded by government, research councils and industry. Areas of interest and expertise include plant pathogen biology, epidemiology, ecology and diversity with particular focus on soilborne diseases such as Sclerotinia and Fusarium and disease management approaches such as biological control and disease forecasting. John has 30 years of pathology experience and strong links with the industry and other researchers through collaborative projects.
