BioGeoChemistry at Interfaces

The focus of this project is to better predict the behavior of metal and carbon cycling in our environment. We identify and quantify biogeochemical processes that control the movement of metals and carbon in the environment, which supports predictive models and identifies potential impacts of precipitation, sea level rise, etc. We are primarily focused on studying the role of biological and geochemical reduction/oxidation (redox)

geochemical reduction/oxidation (redox)

Redox processes require one chemical species that donates electrons and another chemical species that accepts those electrons. As a chemical species donates electrons it is “oxidized,” and as the other species accepts electrons it is “reduced.”

wetland

An area of land that is periodically saturated with water, which influences the types of plants and animals that can live there. Wetlands include swamps, marshes, bogs, and other similar areas.

A chemical reaction that takes place between an oxidizing substance and a reducing substance. The oxidizing substance loses electrons in the reaction, and the reducing substance gains electrons.
