Richard Salisbury Ellis CBE FRS (born 25 May 1950, Colwyn Bay, Wales) is Professor of Astrophysics at the University College London. He previously served as the Steele Professor of Astronomy at the California Institute of Technology (Caltech). He was awarded the 2011 Gold Medal of the Royal Astronomical Society, in 2022 the Royal Medal of the Royal Society and in 2023 the Gruber Prize in Cosmology.
Education
Ellis read astronomy at University College London and obtained a DPhil at Wolfson College at the University of Oxford in 1974.
Career and research
In 1985 he was appointed professor at the University of Durham (with two years at the Royal Greenwich Observatory) for his research contributions. In 1993 he moved to the University of Cambridge as the Plumian Professor and became a professorial fellow at Magdalene College. He served as director of the Institute of Astronomy from 1994 to 1999, at which point he moved to Caltech. Shortly after his arrival at Caltech, he was appointed as director of the Palomar Observatory which he later reorganized as the Caltech Optical Observatories taking into account the growing importance of Caltech's role in the Thirty Meter Telescope. After 16 years at Caltech, in September 2015 he returned to Europe via the award of a European Research Council Advanced Research Grant held at University College London (UCL).
Ellis works primarily in observational cosmology, considering the origin and evolution of galaxies, the evolution of large scale structure in the universe, and the nature and distribution of dark matter. He worked on the Morphs collaboration studying the formation and morphologies of distant galaxies. Particular interests include applications using gravitational lensing and high-redshift supernovae. He was a member of the Supernova Cosmology Project whose leader, Saul Perlmutter, shared the 2011 Nobel Prize for Physics for the team's surprising discovery of the accelerating expansion of the Universe. His most recent discoveries relate to searches for the earliest known galaxies, seen when the Universe was only a few percent of its present age.
At Caltech, Ellis was director of the Palomar Observatory from 2000 to 2005 and played a key role in developing the scientific and technical case, as well as building the partnership, for the Thirty Meter Telescope - a collaborative effort involving Caltech, the University of California, Canada, Japan, China and India destined for Mauna Kea, Hawaii. If constructed this will be the largest ground-based optical and near-infrared telescope in the northern hemisphere.
Awards and honours
He was elected a Fellow of the Royal Society in 1995, appointed a Commander of the Order of the British Empire (CBE) in the 2008 New Year Honours, a Fellow and Corresponding Member of the Australian Academy of Science in 2018, and an International Member of the US National Academy of Sciences in 2024.
