Brandy Gartman, joined Pacific Northwest National Laboratory (PNNL) in 2011 as a post master’s research associate and focused on studying the environmental transport of subsurface contaminants impacting the vadose zone. In 2014 Gartman moved to ViZn Energy Systems, Inc., a grid-scale battery start-up company, as the senior analytical chemist where she built the analytical laboratory while developing a more stable electrolyte. Then she returned to PNNL in 2015 as a radiochemist supporting the National Security Directorate (NSD) where she now leads a series of projects in support of nuclear forensics research.

Gartman’s research is focused on developing clean radiochemistry processes to compliment the radiometric detection capabilities located in the PNNL Shallow Underground Laboratory. Another research focus area has been in support of the Molybdenum-99 Medical Isotope Program, where the importance of this research was acknowledged at an international conference in 2023 .  

Gartman has also been pioneering the development of a new methodology for particle separation that hyphenates mesofluidic separators with field flow fraction. Initially funded under a Laboratory Directed Research and Development project, the continued development of this cross-disciplinary method supports NSD, Environment and Energy Directorate, and Physical and Computational Sciences Directorate mission areas.
