Professor Matthew Ginder-Vogel leads the Environmental Biogeochemistry group at UW Madison. Our group studies the fundamental biogeochemical processes controlling the dynamics of nutrients and contaminants within the environment. In addressing elemental cycling, environmental chemists must consider the complete system, rather than just a simplified fraction. In natural environments, element cycling may be mediated by a variety of processes, such as adsorption/desorption, oxidation, or reduction (abiotic or biotic). Our research combines field-based measurements with simplified lab-based experiments and development of novel measurement techniques, in order to reveal the dominant biogeochemical mechanisms affecting element cycling and mobility in environmental systems.
