Research Interests: 

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.

I am an ecosystem ecologist and biogeochemist whose research is principally concerned with tracking the movement of elements through ecological systems. My research aims to document the extent to which the structure and function of aquatic ecosystems is being altered by land use change (urbanization, agriculture, mining) global change (rising CO2, rising sea levels) and chemical pollution. Ultimately this information is necessary to determine whether and how ecosystem change can be mitigated or prevented through active ecosystem management.
