Research/teaching interests

  • plant and fungal ecology
  • The goal of my research program is to better understand the functioning of fungi in natural and managed systems.  One way that members of my lab group and I work towards this goal is to examine how abiotic and biotic factors interact to affect the abundance and community composition of plant-associated fungi and how changes in these parameters then feedback to affect the performance of host plants. We combine field and laboratory experiments with microscopic and molecular analysis of fungal communities.  Current projects explore how host plant genetics influences fungal abundance and diversity, the impact of climate change on interactions between host plants, fungi and insects, and the belowground mechanisms by which invasive plants may harm native plants.  We also have an interest in tropical systems where we have examined interactions among vertebrates, plants and mycorrhizal fungi in addition to other issues.

This faculty member is also a mentor in the NSF IGERT graduate training program: NAU’s IGERT PhD program seeks to identify key links between genes and the environment and is designed to train exceptional graduate students in molecular genetics, environmental sciences, and spatio-temporal modeling.

Teaching.  I regularly teach Ecology, Mycology, Principles of Biology, and a seminar on Responsible Conduct of Research.  I also participate in a team-taught course on Genes to Environment Research and occasionally offer a course on the Biology of Invasive Species.
