Research Interests

Biogeochemistry, biomineralization and mineral-microbe interactions. Interdisciplinary research on metals, minerals and microbes that explores the fate of uranium and plutonium in the environment. This research is achieved through collaborations with experts in microbiology, genetics, mineralogy, geochemistry, and analytical chemistry to provide novel perspectives on biomineralization.
