Research Categories: ecosystem ecology and biogeochemistry

Current projects: 1. Coupled C, N and S cycling in coastal plain wetlands: how will climate change and salt water intrusion alter ecosystem dynamics? NSF Ecosystems 2010-2013, NSF Coastal SEES 2015-2019, 2. Environmental Implications of Nanotechnology, Center for Environmental Implications of Nanotechnology, Ecological Research Theme Leader, NSF & EPA, 3. Urban watersheds and urban freshwaters: NSF ULTRA, NSF Ecosystems, 4. Environmental impacts of mountain top mining. Foundation for the Carolinas, NSF Hydrology 2014-2017.

Research Description: I am broadly interested in the capacity of ecosystems to retain nutrients and energy, particularly in the face of human accelerated environmental change. My research primarily focuses on how ecosystem carbon and nutrient cycles are altered by climate and land cover change. The majority of my research to date has taken place in aquatic ecosystems, I think about biogeochemistry in a watershed context and am working in upland and floodplain soils as well as stream channels and wetlands in my current research.

Areas of Interest:
Biogeochemistry
Ecosystem Ecology
Stream Ecology
Wetlands Ecology
Urban Ecology
Restoration Ecology
