Biography

Sarah Saslow has over 10 years of experience in fundamental and applied geochemical research. Since joining PNNL in 2015, her work has focused primarily on the immobilization of radionuclides and co-mingled contaminants that persist in nuclear waste streams or that require remediation from the Hanford subsurface. Specifically, her research seeks to understand how radionuclide incorporation into primary and secondary mineral phases may be used to improve current immobilization and remediation strategies. Her expertise in solid phase characterization techniques, including X-ray absorption spectroscopies (XANES/EXAFS), microprobe X-ray fluorescence mapping, XPS, and XRD, is often used to extrapolate the fundamental mechanisms driving material performance. Before joining the PNNL team, Sarah was a PhD student at Northwestern University where she used nonlinear optics (second harmonic generation) to research the chemical and electrostatic properties of mineral/water interfaces and the impact these properties have on metal contaminant transport through the environment.
