Our lab’s goal is to understand the integrated “signals” that flowing waters carry as they move downstream. We use methods from stream ecology, biogeochemistry, and hydrology to address questions about the abiotic and biotic conditions that control how material is transported into and processed within freshwater networks. Research in the lab focuses on: (i) constraining the fate of materials in flowing waters, including micro-plastics, solutes and particulates, (ii) using distributed in situ sensors to identify emergent patterns of terrestrial-aquatic connectivity, and (iii) quantifying the effects of altered hydrologic regimes on water quality and ecosystem function. We work in a diverse array of systems that range from the coastal plains of the Southeast, to river networks draining permafrost landscapes in the Arctic.
