PhD in Geosciences - Crystal Chemistry and Crystallography in Stony Brook United States | Stony Brook University, SUNY

The department boasts extensive expertise in analyzing earth materials at atomic and molecular scales, applying these findings to understand the characteristics of substances forming Earth's layers from surface to core. Two premier research hubs—the Center for Environmental Molecular Sciences (CEMS) and the Mineral Physics Institute (MPI)—focus on upper crustal dynamics and Earth's deep interior, respectively. These centers utilize diverse structural analysis techniques, with some instruments housed locally and others at global synchrotron X-ray and neutron facilities. On-site resources include advanced single-crystal and powder X-ray diffraction equipment, supporting high-temperature and high-pressure research. Current investigations prioritize oxide, hydroxide, sulfide, carbonate, and silicate crystal structures, examining phase transformations, atomic ordering, and ion exchange processes. Proximity to Brookhaven National Laboratory and the National Synchrotron Light Source (NSLS) enables groundbreaking experiments needing intense X-ray beams. Additional research employs X-ray absorption spectroscopy for mineral structure analysis, neutron diffraction for water-containing compounds, and solid-state NMR spectroscopy to study crystal defects and substitutions. Numerous faculty members contribute to developing next-generation beamlines tailored for high-pressure and environmental research, designed to serve both Stony Brook researchers and the broader scientific community. These efforts are enhanced by transmission electron microscopy capabilities for electron diffraction studies.
