Emily is a Postdoctoral Fellow in the Astrobiogeochemistry Laboratory at JPL. Her research is driven by understanding how microbes and the earth interact across spatial scales, within landscapes, and through time. Using laboratory- and field-based studies, she integrates phylogenetic, genomic, and geochemical techniques to illuminate subsurface microbe-mineral interactions and biogeochemical processes within alluvial environments. At JPL, Emily investigates biosignature formation and preservation in subsurface Mars-analog environments.
