Sir Robin MacGregor Murray FRS (born 31 January 1944 in Glasgow) is a British psychiatrist, Professor of Psychiatric Research at the Institute of Psychiatry, King's College London.
Then he started training in psychiatry at the Maudsley Hospital in London and has remained there ever since apart from one year at the National Institute of Mental Health in the USA.
[citation needed] Professor Murray is part of The Psychosis Research Group at the Institute of Psychiatry, perhaps the largest (by number of papers produced per annum) in the world.
In 2009 Murray had a public disagreement with David Nutt in the pages of The Guardian about the dangers of cannabis in triggering psychosis.
[6] Murray previously wrote that while the risk increase is "about five-fold [...] for the heaviest users", the issue has become a political football.
