My laboratory is interested in understanding the ecology and population genetics of plant beneficial and disease causing soil fungi. The ultimate goal of my research program is to generate science-based knowledge to develop improved management approaches that reduce economic losses to plant disease while promoting increased plant health and productivity. For many years, we have studied the soil fungus Rhizoctonia solani, which is an economically important pathogen of species of agricultural and forestry crops throughout the world. However, the fungus can also cause disease on non-cultivated species of plants in natural ecosystems and is of ecological importance as a recycler of organic matter and nutrients in soil. Research conducted in my laboratory has resulted in the development of methods to  identify species of Rhizoctonia fungi to better define populations to advance our understanding of evolutionary history and plant disease ecology. Our research suggests that Rhizoctonia fungi represent a genetically diverse assemblage of species that represent an important early diverging and transitional group of fungi related to mushroom forming fungi. Students in my laboratory also study Rhizoctonia fungi and soil microorganisms that associate with terrestrial species of orchids. Information generated from this collaborative research is being used to better understand the interaction of Rhizoctonia fungi and microbes with soil chemical factors for developing improved approaches to conserve terrestrial species of orchids native to the US. Additional research projects include examining the  influence of beneficial soil fungi on plant flowering and understanding the linkage between fungal diseases of animals and plants.

PP222 Kingdom of Fungi (fall and spring) – This course provides an overview of the diversity of fungi and their ecological, economic and historical impact on the environment and society. The fall course is a taught in a traditional classroom setting (face-to-face) and supplemented with the examination and discussion of fungal specimens. For the spring course, lectures, course content and discussions are presented and delivered in an online, distance education format.

 PP575 Introduction to Mycology (fall, odd years) – This course provides a synthesis and survey of organisms in the Kingdom Fungi. Lectures focus on providing a comprehensive understanding of the biology, diversity, ecology, phylogeny, systematics, and taxonomy of fungi. The laboratory component of this course complement the lectures and involve characterizing, culturing and identifying fungi sampled from diverse ecological habitats.
