I’m Ruby Byrne, an astrophysicist and radio astronomer.

I am a Research Assistant Professor at Caltech, where I study radio astronomy and observational cosmology. My research focuses on developing and operating exquisitely sensitive radio telescopes that can reveal clues about our universe’s early history.

Originally from Portland, Oregon, I studied physics and math as an undergraduate at Macalester College before earning my Ph.D. in physics from the University of Washington. I joined the Astronomy Department at Caltech in 2021.
