Jonathan Price studied medicine at Cambridge and Oxford, completed an undergraduate degree in Physiology and Psychology, and was committed to a career in psychiatry from his first encounter during his undergraduate attachment. Via Shropshire, Nottingham and Birmingham, he returned to Oxford, where he completed his training in adult psychiatry, old age psychiatry, and psychological medicine, and undertook a research fellowship in health services research. He was responsible for the undergraduate course in psychiatry for 16 years, aiming to encourage medical students to pursue a career in a specialty that is absorbing, challenging, moving and inspiring. He now divides his time between Oxford and the hills and waters of North West Wales. John Geddes is Head of Department and Professor of Epidemiological Psychiatry at Oxford University.
