Fields of expertise
Uranium biogeochemistry and isotope geochemistry
Deep subsurface microbes
MissionThe focus at EML is geomicrobiology: specifically, the study of metal-microbe interactions in the subsurface. The fundamental scientific questions are centered on the metabolic activity of microorganisms and their impact on biogeochemical cycling. There are many applications to this general scientific question: e.g., bioremediation, the storage of nuclear waste in geological repositories, the mobility of contaminants in the subsurface. We also specifically probe for the role of Gram-positive bacteria, an important but understudied group of bacteria, in the subsurface.
