RESEARCH INTERESTS

My research projects focus on fungi in most soils worldwide which develop beneficial mycorrhizal symbioses with a wide range of plant species. I curate the International Culture Collection of Vesicular-arbuscular Mycorrhizal Fungi (INVAM) (link to http://invam.caf.wvu.edu), which provides diverse germ plams to examine host, soil, and plant factors optimizing benefit of the mycorrhizal association. Developmental studies of mycorrhiza and spore differentiation and comparisons of fatty acid profiles are being used to elucidate patterns of organismal evolution and speciation. As part of the mission of INVAM, we are collaborating with scientists worldwide to examine patterns of fungal diversity at molecular, organismal, and ecological scales. At a basic level, projects include the study of comparative development of mycorrhiza and spore differentation of selected species to elucidate patterns of organismal evolution and speciation, the role of hyphal glycoproteins in nutrient interactions and soil aggregation, and population level studies isolating native fungi from various sites and determining the proportion of species which are effective growth promoters of assay hosts. At an applied level, projects are underway to screen and produce inoculum of specific fungal isolates for commercial application to promote growth and survival of transplantable plant species in field settings where soils have been disturbed or removed.
