About
Daniela Leitner is a key figure in experimental cosmology, specializing in the precision robotics that enable large-scale spectroscopic surveys. Her primary research focus is the development and deployment of high-accuracy fiber positioning systems for next-generation dark energy experiments. As a core contributor to the Dark Energy Spectroscopic Instrument (DESI), Leitner played a pivotal role in engineering the instrument’s revolutionary multi-object focal plane, which houses 5,020 robotic fiber positioners. Her most-cited work (175 citations) details the installation and performance of this system on the Mayall Telescope, where the robots autonomously retarget optical fibers every 10–20 minutes with micron-level precision—a critical capability for measuring the spectra of 35 million galaxies and quasars. Leitner’s contributions extend to production and rigorous testing of these positioners, ensuring the reliability needed for DESI’s mission to map the Universe’s expansion history using Baryon Acoustic Oscillations. Through her work, she has helped transform robotic fiber positioning from a concept into a proven technology, enabling one of the most ambitious cosmological surveys ever undertaken.
