Coel Hellier is a Professor of Astrophysics at Keele University in the UK, working on extrasolar planets. After undergraduate study at the University of Oxford and a PhD at University College London he was then a Hubble Fellow at the University of Texas at Austin before moving to Keele.
In 2004 Keele joined the WASP consortium (Wide Angle Search for Planets) to search for transiting exoplanets. Professor Hellier leads the team which built and now operates the WASP-South camera array, hosted at the South African Astronomical Observatory. Over the last decade WASP has become the most productive of the ground-based transit searches with over 140 discoveries, including many that are prime targets for characterisation with the Hubble Space Telescope and the imminent James Webb Space Telescope.
