Our research focuses on how terrestrial ecosystems work, with an emphasis on what controls the exchanges of gases and energy between land surfaces and the atmosphere. This research is relevant to several environmental problems, including understanding changes in climate and global biogeochemistry. Our approach is interdisciplinary, borrowing techniques and ideas from a range of academic disciplines including plant physiology, community and ecosystem ecology, hydrology, micrometeorology, environmental physics, and biogeochemistry.

We are currently focusing on five projects:

• What controls Tropical Forest CO₂ exchange?
• What controls wetland productivity?
• How do Boreal Forests recover from fire?
• How will climate change affect Southern Californian's ecosystems?
• What is California's Carbon budget?
