I am interested in the biology and management of diseases of forest and shade trees. I have particular interests in the spatial occurrence of forest diseases and insects and their relationships to environmental factors including metrological conditions. We are continuing to explore the influence of environmental conditions on disease occurrence of native and exotic rusts, cankers and root diseases.

Courses I Teach:

Integrated Tree Health Management (BSPM 365) (Fall)

Forest Health Issues (BSPM 521) (Fall Even Years)
