OverviewAI-generated summary

Shannon L. Speir's research investigates the complex interactions between land management practices, particularly in agricultural settings, and their impact on nutrient mobilization and transport within watersheds. Her work examines how factors such as storm size, the use of cover crops, and the modification of hydrologic systems influence the movement of nitrogen and phosphorus. Speir also studies the underlying biogeochemical processes, including denitrification and nitrous oxide production in river sediments, and how environmental factors like temperature and carbon availability affect these processes.

Her scholarly contributions include publications in journals focusing on environmental science and hydrology. Speir's research metrics indicate a scholarly impact with an h-index of 12 and over 400 citations. She has also received federal funding, including an NSF I-Corps grant totaling $50,000 for research on peptoid microsphere-coated surfaces for wound healing applications. Speir collaborates with researchers at institutions including the University of Arkansas at Little Rock and the University of Arkansas at Fayetteville, contributing to a network of scientific inquiry.
