Gregory Starr received a Ph.D. in Biological Sciences from Florida International University in 2000 and completed his postdoctoral research at the University of Florida. He was appointed Assistant Professor at the University of Alabama in 2008, and Associate Professor in 2013.

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. For more detailed information regarding my current research projects visit the Starr Laboratory Site.

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.

Everglades Saw Grass Prairie.

Long Leaf Pine Canopy and Eddy Covariance Equipment at the Joseph W. Jones Ecological Research Center.

Research Opportunities

Motivated undergraduate and graduate students interested in joining my laboratory should contact me directly, 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.
