I am a stream ecologist interested in anthropogenic influences on biogeochemical cycles in stream ecosystems, focusing on nitrogen and carbon cycling in headwater and wadeable streams. In my research I use whole-stream field methods and laboratory techniques to understand linkages between the stream nitrogen and carbon cycles. My dissertation research focused on understanding how land use practices in stream basins and in riparian zones increased inorganic nitrogen concentrations with consequent changes to nitrification, denitrification, and whole-stream nitrogen cycling. Since returning to the nitrogen-limited streams of the Pacific Northwest, I have begun researching how adding wood to streams during restoration affects whole-stream nitrogen and carbon cycling. Large wood addition typically alters stream ecosystem structure by altering channel geomorphology and changing the contribution of benthic and hyporheic nitrogen cycling processes. Through my research, I hope to gain a better understanding of how humans change stream ecosystem processes, and my ultimate goal is to contribute to best management practices related to stream restoration.
