Mike Jones is Professor of Experimental Cosmology at Oxford University, where he leads a group designing and building radio telescopes of assorted shapes and sizes, from small single antennas to the Square Kilometre Array. Mike studied physics and electrical engineering at Cambridge, graduating in 1986, and then went on to do a PhD building a radio telescope to study clusters of galaxies and measure the Hubble constant, the rate at which the Universe expands. He designs, builds and uses novel types of radio telescope for observing the cosmic microwave background. These observations tell us about the age, composition and history of the Universe and are one of our best ways of studying the Big Bang.
