Professor Martin Rees is a British cosmologist, astrophysicist, and the 15th Astronomer Royal, a post first established in 1675, and to which he was appointed in 1995.

Professor Rees has a BA, MA, and PhD from Cambridge, supervised by Dr. Dennis Sciama, and after his postdoctoral studies in the UK and abroad, later worked as a professor at Sussex University, the University of Cambridge, and Gresham College. He has also been the director of the Institute of Astronomy and later the Master of Trinity College at Cambridge.

Professor Rees has authored over 500 research papers and numerous books, and made contributions to the origin of Cosmic Microwave Background Radiation, black hole formation, quasars, gamma-ray bursts, as well as more expansive topics in anthropic reasoning and the multiverse. He has also been a supporter of the SETI project, and chaired to advisory board for the Breakthrough Listen project funded by Yuri Milner.“
