John Ruhl

Biography

Over the past 25 years John Ruhl has built and used instruments to measure the properties of the Cosmic Microwave Background radiation, a remnant glow from the Big Bang. His current projects focus on finding a signature of Cosmic Inflation imprinted by gravity waves created at the birth of our universe. These measurements – done from the South Pole station in Antarctica and from stratospheric balloons – have taught us an enormous amount about the cosmos, which we can only understand in the context provided by General Relativity.
