We use biogeochemistry and ecosystem analysis to study global change, with emphasis on surface water bodies and watersheds. We prioritize long-term and large-scale studies, often through projects that are regional or international in scope. We value data. Interests include linkages between ecosystem types (e.g., river-lake), consequences of dams, importance of winter and seasonality, pollution legacies, as well as agricultural and urban fluxes associated with 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, multi-site collaborations? Implications of ice loss? Spatial and temporal patterns in reservoirs, their tributaries, or reservoir-fed rivers?
Let’s talk.
