About
Brian Walls is a key figure in the development of next-generation astronomical instrumentation, with his work centered on the Giant Magellan Telescope (GMT), a 24-meter-class observatory poised to revolutionize ground-based astronomy. His primary research areas include high-resolution optical and infrared spectroscopy, precision radial velocity measurements, and the engineering of complex spectrographs for extremely large telescopes. Walls has made major contributions to the design and construction of GMT’s first-generation science instruments, which include both infrared and visible light spectrographs capable of delivering wide-band imaging to ultra-high-resolution spectroscopy (R~200,000). Notably, he has led the development of GCLEF, an optical spectrograph operating from 350-950 nm designed for high-resolution and precision radial velocity work, which has advanced from preliminary to final design stages under his guidance. His 2016 paper on GMT instrumentation progress, with 14 citations, remains a foundational reference for the project’s technical community, while his 2022 update continues to inform ongoing instrument development. Walls’s work is critical to enabling discoveries in exoplanet characterization, stellar astrophysics, and galaxy evolution, establishing him as a driving force in the GMT’s scientific mission.
