About

Parker Fagrelius is a key figure in experimental cosmology, specializing in the design and implementation of large-scale spectroscopic instrumentation. Their primary research focuses on advancing the technology behind the Dark Energy Spectroscopic Instrument (DESI), a Stage IV ground-based experiment aimed at unraveling the mysteries of dark energy through precise measurements of baryon acoustic oscillations and the growth of cosmic structure. Fagrelius has made major contributions to the development of DESI’s robotic multi-object focal plane system, a groundbreaking array of 5,020 fiber positioners that autonomously retarget optical fibers every 10–20 minutes with micron-level precision. This work, detailed in a 2022 paper with 175 citations, is critical for enabling DESI to measure over 40 million galaxy redshifts. Their earlier involvement in the DESI instrument design (2016, 234 citations) and the fiber view camera system (2019) further underscores their role in building the experiment’s core infrastructure. With cumulative citations exceeding 489, Fagrelius’s engineering innovations are foundational to one of the most ambitious dark energy surveys ever undertaken, directly impacting our understanding of the universe’s expansion history.
