About
Paul Perry is a key figure in astronomical instrumentation, whose work has directly enabled next-generation cosmic surveys. His primary research focuses on the design and deployment of fiber positioners for multi-object spectrographs, the robotic systems that precisely align hundreds or thousands of optical fibers to capture the light from distant galaxies. Perry’s major contribution is his leadership in developing the R-θ fiber positioner for the BigBOSS instrument (now DESI), a critical component that allows for rapid, accurate fiber placement across a wide focal plane. This innovation is foundational to DESI’s ability to measure the redshifts of over 20 million galaxies, mapping the universe’s expansion history across the last 8 billion years—a volume 10-20 times larger than previous surveys. His seminal 2012 paper detailing the positioner’s design and performance has garnered 7 citations, reflecting its influence on the field. Perry’s work has been instrumental in transforming ambitious cosmological proposals into operational reality, providing astronomers with the tools needed to probe dark energy and the large-scale structure of the cosmos.
