About

David H. Brooks is a leading figure in astronomical instrumentation, with a career focused on building the complex control systems that power next-generation observatories. His primary research area is the development of robotic focal plane technology and instrument control architectures for large-scale spectroscopic surveys. Brooks's most notable contribution is his central role in the Dark Energy Spectroscopic Instrument (DESI), a revolutionary instrument for the Mayall 4-meter telescope at Kitt Peak. He has been instrumental in designing and testing the control systems for DESI's 5,000 robotically positioned fiber-optic positioners, a feat of engineering that enables the instrument to map tens of millions of galaxies and quasars. His 2018 paper on the DESI instrument control systems, which has garnered 6 citations, details the early testing and status of this complex system. This work is foundational for DESI’s mission to unravel the mystery of dark energy. Brooks’s expertise in precision robotics and real-time control is critical to the success of one of the most ambitious cosmological surveys ever undertaken, cementing his reputation as a key architect of modern astronomical hardware.
