Research Interests
My research focuses on understanding the controls over carbon, water, and energy fluxes through terrestrial ecosystems. This includes the interaction between abiotic and biotic processes and the feedbacks to global biogeochemical cycles and climate change. I am particularly interested in understanding these processes across multiple scales (e.g. internal plant signals to continental level carbon dynamics) using plant physiological ecology as a foundation for my research. My research makes use of the latest environmental instrumentation to understand the relationships among climate, biogeochemistry, and plant physiology.

Ecosystems of Study
Over the past decade I have been involved with research in a multitude of ecosystems around the world, these include but are not limited to: Arctic Tundra, Everglades, Southern Pine, and Lowland Neo-Tropical Rain Forest Ecosystems. I would encourage my students to focus their studies on these ecosystems but I would not restrict them to these systems.

Research Opportunities
Motivated undergraduate and graduate students interested in joining my laboratory should contact me directly, gstarr@bama.ua.edu. Interested individuals should be open to working on ecosystem or individual species addressing questions associated with plant physiological ecology, ecosystems ecology, or atmospheric transport. Both basic and applied approaches are appropriate. I expect all students to incorporate ecological theory into their studies.
