My laboratory is interested in understanding the ecology and population genetics of soil fungi that cause plant disease. The ultimate goal of my research program is to generate science-based knowledge that will result in the deployment of improved disease management approaches that reduce economic losses to plant disease while promoting increased productivity, sustainability and plant health. For many years we have studied the soil fungus Rhizoctonia solani, which is an economically important pathogen of agricultural and forestry crops throughout the world. However, the fungus can also infect non-cultivated species of plants in natural ecosystems and is of ecological importance as a recycler of nutrients in soil. Research conducted in my laboratory has provided a conceptual framework for identifying species of R. solani to better define populations to advance our understanding of the evolutionary history and disease ecology of the fungus. Our research suggests that R. solani is not a single species, but is a genetically diverse assemblage of species that represent an important early diverging and transitional group of the mushroom forming fungi. Current research in my lab is focused on the use of “omic”-based methods to better understand the genetic basis of how R. solani produces microsclerotia, which are structures that promote long-term survival of the fungus in soil in absence of a plant host. More recently we have been involved in the study of Rhizoctonia fungi associated with terrestrial species of orchids. These fungi benefit orchids by increasing seed germination and seedling growth. Information generated from this collaborative research project is being used to develop improved approaches to conserve terrestrial species of orchids native to the US.

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.
