We study fungal ecology, evolution, and systematics, with a special focus on fungal endophytes. We focus on plant communities ranging from Arctic tundra to hot deserts, tropical forests, and agroecosystems. Our diverse projects are united by an interdisciplinary approach and our passion for organismal biology.
