Scholarship/Creative Work

We study how plants and microorganisms influence the cycling and storage of carbon and nutrients in terrestrial ecosystems, and often consider how these processes influence ecosystem responses to climate and environmental change. Our approaches are often integrative, and combine field and laboratory experiments with large-scale data analysis. Students interested in getting involved are welcome to reach out to Prof. Allison Gill any time!

*I am on leave and not teaching courses for the 2023-2024 academic year.
