Elizabeth M. Herndon

Asst. Professor
I am an environmental geochemist interested in the interactions between minerals, water, and biota that shape the Critical Zone – the thin surface of the Earth’s crust from groundwater to canopy that supports life. In particular, my research focuses on anthropogenic perturbations of soil geochemistry, both direct impacts of metal contamination and land use and indirect impacts due to climate change. Additionally, I’m interested in how these perturbations influence the transport of elements through watersheds, e.g. from air into soils, and from soils into vegetation and river systems.

In order to examine biogeochemical processes across multiple scales, my research incorporates a variety of methods such as field sampling, mesoscale laboratory experiments, analytical techniques (both in-house and at national laboratories), and theoretical modeling. Recent projects include: 1) Characterizing the potential influence of warming on organic carbon degradation in tundra soils in the Arctic, and 2) Quantifying the biogeochemical cycling of manganese contamination at the Shale Hills Critical Zone Observatory in central Pennsylvania.
