We study global change, with emphasis on surface water bodies and watersheds, often using data-intensive approaches to understand large-scale pattern and process. Interests include freshwater-climate interactions, watershed biogeochemistry, interactions between ecosystem types (e.g., river-lake connections), environmental data synthesis methods, dams, seasonal cycles, and the “food-energy-water nexus.”

Would you like to know more about legacy phosphorus? Long-term ecological time series? Tools and principles for data-intensive collaborations? Implications of ice loss? Spatial and temporal patterns in reservoirs, their tributaries, or reservoir-fed rivers?
Let’s talk.
