Research Scientist (Chemist)


Quin Miller has been a staff member at PNNL since 2019 and has also worked at PNNL as a post-bachelor’s research associate, intern, visiting researcher, and postdoc prior to becoming a research scientist. He studies geochemically relevant physicochemical interfacial processes with PNNL’s in situ experimental suite, including in situ X-ray diffraction, infrared spectroscopy, and nuclear magnetic spectroscopy. He also works on a broader range of projects that include CO2 storage via basalt mineralization, subsurface metamaterial sensing technology research and development, and associated upscaling to planned field deployments.

Miller is always eager to collaborate, especially with regards to projects that may benefit from PNNL’s world-unique in situ X-ray diffraction, capable of probing fluid-solid reactions at subsurface temperatures and pressures.
