We are interested in understanding how Earth surface, in particular water flow and chemistry, responds to climate and human induced perturbations.

Watersheds are the fundamental earth surface units that respond and adapt to changes in external forcings, and process key elements (e.g., C, N, P). These processes govern biogeochemical transformation and chemical spreading from non-point sources, and regulate water quality and quantity. Our group studies the interactions between water flow and biogeochemical processes shaped by external climate conditions and internal structure characteristics. We collaborate with a broad group of biogeochemists, hydrologists, ecologists, and geologists; and study watersheds under gradients of climate, vegetation, geology, and land use conditions across the globe, as shown below.
