Biography
Sandra Taylor is a staff scientist in the Physical Sciences division at Pacific Northwest National Laboratory (PNNL). She broadly studies crystallization mechanisms, including crystal growth, dissolution, and sorption of dissolved ions. She leads sophisticated lines of research developing and using high-resolution mass-sensitive chemical imaging and mapping capabilities at PNNL to characterize materials. Her research is cross-cutting, spanning the fields of biogeochemistry to corrosion science to novel materials synthesis.
Taylor is always eager to collaborate, especially in regards to exploring the chemical reactivity of materials and interfaces using atom probe tomography.
