Biography

Sherry L. Cady is an expert on how microbes and their organic remains alter the minerals and sediments that precipitate and accumulate in their presence. Her research on microbe-mineral interactions helps to reveal the types of signatures microbes leave behind in different types of environments, whether they are sequestered carbon-bearing molecules in soils, a topic relevant to the DOE, or small and degraded amounts of carbonaceous residues in ancient rocks, a topic relevant to NASA and NSF. A better understanding of the mechanisms that lead to the sequestration of molecular-scale evidence of microbes in geological materials will improve our ability to predict how microbial communities respond to environmental and climate changes. Such research has implications in the search for microbial life throughout Earth’s geological record and will inform the search for evidence of microbial life beyond Earth.
