Our research explores the functional roles of microbes in ecosystems. Microbes, such as bacteria and fungi, contribute to global carbon balance and cycle nutrients required for plant growth. Using theory, experiments, and mathematical models, we analyze the response of microbial communities to changes in the environment and the consequences for life on Earth. Much of our work focuses on the soil microbiome and feedbacks to global climate change. We also recognize the growing need to manage ecosystems and their microbial inhabitants in the face of human environmental pressures. We aim to provide a sound scientific basis for solving environmental problems, including climate change, at local to global scales. The Allison Lab promotes diversity and inclusivity in all of these efforts.
