Biography

Jacqueline Hager began working at Pacific Northwest National Laboratory as a Science Undergraduate Laboratory Intern during the summers of 2015 and 2016. During these internships, she performed laboratory experiments to determine the effectiveness of bioremediation for the iodine groundwater plume present at the Hanford Site. Hager returned to PNNL in 2017, as a post-bachelor research assistant to work on laboratory and field work projects mainly centered around biogeochemistry and environmental characterization and remediation. After earning her master’s degree in 2021, Hager began working as an Earth scientist. She is primarily focused on two topics: groundwater remediation—specifically on testing ion exchange resins for pump-and-treat applications—and glass corrosion in the environment, specializing in evaluating biocorrosion of glasses by soil and subsurface microbes.
