Dr. Yee’s academic interests are in the fields of geochemistry and geomicrobiology. The goal of his research is to understand the impact of microorganisms on the geochemical cycling of inorganic elements. He employs microscopic, spectroscopic, and genetic techniques to investigate microbe-mineral interactions and the biotransformation of anthropogenic contaminants. The principal area of Nathan’s current work is focused on understanding molecular pathways of microbial-catalyzed redox reactions.
