Research Program

My research interests are in the area of microbial ecology and the biological and integrated control of plant pathogens. Most of our attention has been directed to the fungi. Our research can be viewed from three perspectives: (1) basic studies on microbial community development on plants, including adhesion and colonization; (2) application of ecological theory to microbes; and (3) applied research on the biological control of the apple scab disease. More specifically, our studies to date have included: assessment of pesticidal impact on microflora from apple leaves and leaf litter; evaluation of microbial antagonism to the apple scab fungus; implications of r- and K-selection and island biogeographic theory to microbial systems; the microbial ecology and pathology of watermilfoil in the Madison area lakes; population biology of Aureobasidium pullulans on leaves; life history theory for unitary and modular organisms.
