Emily S. Bernhardt, Associate Professor  

Emily S. Bernhardt

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.
