Eric Davidson is interested in biogeochemistry and nutrient cycling in terrestrial ecosystems including the effects of management, land use change, and climatic change on soil C and N stocks, trace gas emissions from soils, and leaching of plant nutrients to streams and groundwater. He currently conducts work in the Brazilian Amazon Basin and Cerrado region as well as the forests of New England.

Jake Hagedorn is interested in soil biogeochemistry, hydrology, and agriculture.  His current research focuses on using soil chambers to measure gas emissions in an agricultural landscape framed by managed water level changes.  Hagedorn successfully defended his dissertation and submitted it to the UMD graduate school in the summer of 2022. He is currently teaching at the University of North Carolina at Ashville.

Rachel Nifong’s research interests include the stoichiometry of organisms across abiotic gradients. She investigated how the impact of fire and land use change affects ecosystem resiliency in Eastern Amazonia.  Rachel is now Research Hydrologist at the USDA-ARS Southeast Watershed Research Lab in Tifton, GA.
