About
Brian DiGiorgio Zanger is an instrumental astronomer whose work is central to the design of next-generation ground-based observatories. His primary research focus is the development of cutting-edge spectrographs, particularly for extremely large telescopes. Zanger’s most significant contribution is his leadership in the trade study for the Wide Field Optical Spectrometer (WFOS), a first-light instrument for the Thirty Meter Telescope (TMT). His 2018 paper, which has garnered 7 citations, critically compared slicer versus fiber-based optical designs for this ambitious project. This study was instrumental in determining the optimal architecture for a spectrograph that will deliver a minimum resolution of R~5,000 over a simultaneous 31-wavelength range, enabling transformative observations when TMT begins operations in 2027. By resolving key engineering challenges for this facility-class instrument, Zanger is helping to define the observational capabilities that will serve the astronomical community for decades. His work exemplifies the crucial, behind-the-scenes role of instrument scientists in making future discoveries possible.
