Our research focuses on the physiological responses of plants to environmental variability and resource availability. Defining these relationships contributes to a greater understanding of ecosystem processes and responses to our changing climate.

We use experimental and observational studies to examine plant physiological and growth responses to water availability and changes in temperature. Typically, these questions require gas exchange measurements, sensor networks, flux towers, stable isotopic analyses, and the development of statistical and process-based models. Historically, most of our work has focused on processes in grasslands, savannas, and tree-grass interactions.
