The University of Western Australia has paid tribute to a British scientist killed in a car crash hours after arriving in Perth.
The 36-year-old was in a taxi with 28-year-old Kuldeep Singh in the early hours of Friday when they were hit by a man driving a stolen car.
Both men were killed in the collision while the driver of the stolen car suffered a broken leg and was charged with two counts of manslaughter.
The scientist was in Perth to give a presentation at a conference on quantum physics being jointly organised by the University of WA (UWA) and the University of Queensland (UQ).
The universities issued a joint statement on Sunday expressing "profound sadness" at the deaths.
"(He) was an outstanding young physicist funded by a Royal Society Fellowship at Imperial College, London," UWA acting vice chancellor Bill Louden said.
"He was making significant impacts in the research field for which he had so much enthusiasm and passion."
Professor Louden said Dr Barrett had left an "enduring impression" on colleagues at UQ, where he was employed early in his career.
"(His) strength of character and insight drew colleagues and friends to him throughout his life," he said.
"He was at the height of his career and leaves behind an outstanding research record.
"His tragic and sudden death is a profound loss to the research community."
The scientist was a graduate of Churchill College at the University of Cambridge, where he completed his PhD.
He also held research positions at Hewlett-Packard Labs in Bristol and Macquarie University.The conference will go ahead and will be dedicated to his memory.
