We study ecosystems and global change, with emphasis on surface waterbodies and watersheds, often using data-intensive approaches to understand pattern and process at multiple scales extending from local to continental. Interests include water-climate linkages, watershed biogeochemistry, environmental data synthesis methods, spatial limnology, sensors, seasonal cycles, dams, and the “food-energy-water nexus.”

Would you like to know more about spatial and temporal patterns in aquatic systems? Consequences of ice loss and warming? Legacy phosphorus? Tools and principles for data-intensive collaborations?
Let’s talk.
