Jackie Wells is a part of the Signatures group within the Energy and Environment Directorate (EED) at Pacific Northwest National Laboratory (PNNL). She began working at PNNL as an intern in the Science Undergraduate Laboratory Internship program during the summers of 2015 and 2016. At that time, she performed laboratory experiments to determine the effectiveness of bioremediation for the iodine plume present at the Hanford Site.

Jackie returned to PNNL in 2017 as a post bachelor’s research assistant to work on laboratory and field work projects, primarily focused on biogeochemistry and environmental characterization and remediation.
