Sonu Shamdasani (born 1962) is a London-based author, editor, and professor at University College London. His research and writings focus on Carl Gustav Jung (1875-1961), and cover the history of psychiatry and psychology from the mid-nineteenth century to current times. Shamdasani edited the first publication of Jung's major work: Liber Novus, The Red Book. Although its title had been well known for years, it was not until 2009 that its contents were revealed to the public and practicing psychotherapists.
