Research Interests:

I am retired now, but still remain interested in the biology and management of diseases and insects 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. My graduate students have researched such diverse topics as environmental relationships and occurrence of cankers, root diseases, and rusts, and the biology of bark beetles and their hosts and impacts on fire and fuels, pathway analysis of firewood and exotics, and the impact of dust control chemicals.
