Jonathan Flint is a psychiatrist and geneticist who studies the genetic basis of behaviour. His work has identified mutations that cause intellectual disability, and he has developed strategies that identify genes and sequence variants underlying complex behavioural traits, particularly anxiety and depression. His research has implications for psychology, psychiatry and for animal behaviour.

He was trained in medicine at St. Mary’s Hospital, London and at Oxford University, and in psychiatry at the Maudsley Hospital in London. After 25 years at the University of Oxford, where he was a fellow of Merton college and a Wellcome Trust Principal Fellow, in 2016 he joined the department of psychiatry of the University of California, Los Angeles where he is the Billy and Audrey Wilder Professor of Psychiatry and Neuroscience.
