About

David Correll is a leading figure in precision astronomical instrumentation, with a particular focus on robotic fiber positioning systems for multi-object spectroscopy. His most influential work centers on the development of the Starbug concept—a revolutionary focal plane positioning system that deploys multiple payloads, including pickoff optics and optical fibers, with remarkable accuracy. Correll’s landmark paper, “It’s alive: performance and control of prototype Starbug actuators” (2006, 7 citations), details the prototyping and trialling of novel actuator technologies that bring this vision to life. This foundational research has been instrumental in enabling next-generation survey telescopes to simultaneously observe hundreds of celestial targets, dramatically accelerating the mapping of the universe. Beyond his technical contributions, Correll is recognized for bridging the gap between mechanical design and real-time control, ensuring that Starbug actuators achieve the repeatability and speed required for large-scale astronomical surveys. His work continues to inspire innovations in robotic positioning, making him a key figure in the engineering of modern observational astronomy.
