About

David L. Terrett is a leading expert in astronomical instrumentation, with his primary research focus on the development of fibre positioning systems for large-scale spectroscopic surveys. His most impactful work centers on the WEAVE spectrograph for the William Herschel Telescope, where he pioneered the algorithms that precisely control over one thousand "pick and place" optical fibres. This critical contribution, detailed in his highly cited 2014 paper, enables the rapid and accurate configuration of fibres to capture light from thousands of celestial objects simultaneously. By solving the complex computational challenges of fibre positioning, Terrett’s work has been instrumental in making WEAVE a powerful facility for wide-field optical spectroscopy, with his foundational paper accumulating 13 citations that underscore its importance to the field. His achievements place him at the heart of next-generation survey instrumentation, directly enabling transformative studies in galactic archaeology and cosmology.
