About
Stefane Caseiro is a leading engineer in astronomical instrumentation, specializing in the precision robotics that power the world’s largest multi-object spectrographs. Her core research focuses on the design, control, and calibration of miniature SCARA and theta/phi fiber positioner robots—the tiny, high-speed actuators that place optical fibers with micron-level accuracy to capture the light of thousands of stars and galaxies simultaneously. Caseiro made pivotal contributions to the Dark Energy Spectroscopic Instrument (DESI), the Sloan Digital Sky Survey V (SDSS-V), and the MOONS spectrograph for the Very Large Telescope. Her work on the DESI fiber positioner testing program (5+ citations) directly supported the instrument’s ability to map 35 million galaxies, while her optical test procedures (6 citations) established industry-standard calibration methods for these complex systems. With her most-cited paper (8 citations) on precision control of miniature SCARA robots, Caseiro has helped enable the next generation of massive spectroscopic surveys, decoding the history of the Milky Way and the expansion of the Universe. Her engineering achievements are foundational to modern observational astrophysics.
