Ecosystem Dynamics and Forecasting
Ecosystem: We study the forest and freshwater ecosystems upon which society depends
Dynamics: We model how ecosystems change over time in response to land-use, climate change, atmospheric deposition, and management. We measure carbon, water, and energy exchange between ecosystems and the atmosphere using eddy-covariance and biometeorology sensors.
Forecasting: We predict the future of ecosystems by combining observations and ecosystem models using statistical techniques.

Projects
Ecological Forecasting Initiative Research Coordination Network (DEB-1926388)
Lead PI of an NSF sponsored 5-year project that is leading workshops, conferences, and collaborative software development to address the following objectives:
- Define community standards and best practices for developing, sharing, and archiving forecasts and models
- Increase the number and diversity of NEON-enabled (National Ecological Observatory Network) forecasts by developing and hosting the NEON Ecological Forecasting Challenge
- Create educational materials to empower scientists at all career stages to forecast using NEON data products
- Support the creation of software to produce NEON-enabled forecasts at intensive and collaborative coding-focused workshops
- Align forecast outputs and decision support with the needs of forecast users at mission-driven agencies to guide decision making, and
- Synthesize forecasts to examine how limits to forecastability vary across ecological systems and scales.
