Ecosystem Ecology
Climate change
Current research: 

I am broadly interested in the impacts of climate variability and land-use change on land-atmosphere exchanges of water, energy, and trace gases. I also seek to understand how ecosystem responses to global change can feedback to slow or accelerate future climate change. My research and training is in micrometeorology, hydrology, and ecosystem ecology. I focus on biosphere-atmosphere interactions in a variety of climates and ecosystems, with a current focus on wetland ecosystems. We collaborate with a broad group of researchers and institutions to help inform and advance climate policy.
