About

Don Carlos Abrams is a key figure in astronomical instrumentation, specializing in the development of fiber-fed spectrographs for wide-field optical spectroscopy. His primary research focus lies in the design, assembly, and metrology of high-precision fiber positioning systems, a critical technology for next-generation multi-object spectrographs. Abrams’s major contributions center on the WEAVE spectrograph for the William Herschel Telescope (WHT) in La Palma, where he led the development of innovative "pick and place" fiber positioners capable of accurately deploying over 960 fibers. His work on fiber positioning algorithms, detailed in his most-cited paper (13 citations), and the final assembly and metrology of the positioner (6 citations) have been instrumental in enabling WEAVE’s ambitious surveys. With over 29 total citations across his key publications, Abrams has demonstrated significant impact in advancing the precision and multiplexing capabilities of astronomical instruments. His achievements include overseeing the final testing and integration of the WEAVE fiber positioner, a complex system that will facilitate groundbreaking studies in galactic archaeology and cosmology. Abrams’s contributions are essential to the success of WEAVE, positioning him as a leading engineer in the field of astronomical instrumentation.
