Rebecca Neumann

Dr. Neumann leads that hydro-biogeochemistry research group, which works to advance mechanistic understanding of subsurface flow and biogeochemical reaction processes that impact water and food quality and influence global climate change; mechanistic understanding of these processes is required for the development of sound management strategies that protect human and environmental health.

Current research projects include determining how the micro-nutrient (zinc) and toxin (arsenic) content of rice may change in the future with climate change; identifying the source of organic carbon fueling arsenic mobilization in groundwater of South and Southeast Asia; arsenic mobilization, bioaccumulation and eco-toxicity in urban lakes; remediation of arsenic contaminated groundwater; rice field irrigation management to reduce arsenic exposure; and plant controls over methane production and methane oxidation in permafrost wetlands.
