Biography

Hope Lackey is a Washington State University (WSU) PhD student in analytical chemistry completing a doctoral internship at Pacific Northwest National Laboratory (PNNL). As an intern in PNNL’s Nuclear Chemistry & Engineering group, her post-graduate research focuses on conducting independent research to advance the application of spectroscopy and electrochemistry in the analysis of nuclear fuel cycle systems.

Her skills are being applied to issues associated with separations and monitoring for nuclear materials processing. Her work focuses on increasing the accuracy of real-time system monitoring, which can improve the efficiency of operations and reduce waste production, helping improve worker and environmental safety during the processing of nuclear materials.

Lackey is also an Achievement Rewards for College Scientists (ARCS) scholar, selected by the ARCS Foundation to help advance science and technology in the United States.
