Ecology and biology of fungal and nematodal soilborne pathogens and the integrated management of their resultant root diseases; special interests in diseases of vegetable and food legume crops; microbial interactions; biological control; cultural practices for disease management; and soil-IPM/soil health issues.
After devoting more than 42 years to studies of Fire Blight, the Beer Program transitioned in 2010 to studies of bacterial rots of onions. The program developed contemporary techniques that facilitated identification of bacterial rot pathogens "new" to NY. Control trials are currently under study in collaboration with growers and CCE Specialists.
Ecology of fungal and oomycete pathogens in natural ecosystems; plant-soil feedbacks; invasion biology and the role of pathogens in facilitating invasive success; biology and ecology of oomycetes, especially species in the genus Pythium Eric Nelson's lab: Ecology of Oomycetes
Quantitative epidemiology, focusing on model development and other quantitative measures for the practical management of fruit and vegetable diseases; understanding the biological processes responsible for disease development; elucidating the role of weather and plant disease
