About
John Moustakas is a leading figure in the engineering and analysis of the Dark Energy Spectroscopic Instrument (DESI), a revolutionary Stage-IV ground-based observatory. His primary research areas center on the design, calibration, and data optimization of massive spectroscopic surveys, with a specific focus on the robotic fiber positioning systems that enable DESI to map the cosmos. Moustakas has been instrumental in the development and deployment of the instrument’s 5,020 robotic fiber positioners, which automatically retarget with micron precision every 10–20 minutes, a feat detailed in his highly cited 2022 paper (175 citations). He also led the characterization of fiber assignment incompleteness and its mitigation for DESI’s Data Release 1, ensuring unbiased clustering measurements crucial for cosmology. His work contributed to the first detection of the baryon acoustic oscillation (BAO) signal from early DESI data (37 citations), a key milestone in probing dark energy. With over 300 total citations across his most influential papers, Moustakas’s contributions are foundational to DESI’s mission of measuring 40 million galaxy and quasar spectra to create the largest 3D map of the universe.
