We're broadly interested in the ecology and evolution of plant-fungal symbioses. We use classic microbiological methods, ecological sampling techniques, molecular tools, and the robust framework of phylogenetic biology to understand fungal biodiversity, the ecological roles and evolutionary importance of cryptic microfungi, and the evolution of symbiotic lifestyles across the fungal tree of life. Our field sites range from the Canadian Arctic to lowland rainforests in Panama, and our interests range from bacterial symbionts of fungi to the effects of soilborne molds on tropical forest dynamics. Our diverse projects are united by a passion for organismal biology and our interdisciplinary approach to addressing biological questions.
