About

Katie Grabowski is a key figure in the development of the Sloan Digital Sky Survey V (SDSS-V), the first all-sky, multi-epoch, optical-to-infrared spectroscopic survey. Her primary research areas include astronomical instrumentation, fiber optics, and survey operations—critical work that enables SDSS-V’s ambitious panoptic mapping of the sky. Grabowski’s major contributions include leading the on-sky performance verification of SDSS-V’s new wide-field corrector, a three-element design that replaced the previous two-element system to improve infrared optimization and eliminate the aspherical focal surface. She also spearheaded the field retermination of high-fiber count MTP connectors for the APOGEE spectrograph at Apache Point Observatory, documenting lessons learned, wear analysis, and throughput improvements that directly enhanced the survey’s data quality. Her most cited work, the 2025 paper on SDSS-V’s pioneering panoptic spectroscopy (25 citations), establishes her as a driving force in next-generation astronomical surveys. With additional publications detailing the corrector’s on-sky performance and fiber connector retermination (3 citations each), Grabowski’s work ensures SDSS-V can map millions of stars and galaxies across both hemispheres, advancing our understanding of the Milky Way and the universe.
