Research Statement

Research in the Ehleringer Lab focuses on ecological processes and the bridging of biology with atmospheric science, geology, geography, modeling, and the social sciences. Of particular interest are projects addressing ecological changes, regional climate changes, land-use changes, sustainability, and urban ecology. Jim is currently helping to develop research projects  and training infrastructure in these areas through the development of the Global Change and Sustainability Center.
