Prof. Paul J. Harrison, M.A., B.M., B.Ch., D.M. (Oxon), F.R.C.Psych.

  • Professor of Psychiatry and Associate Head of Department (Research), University of Oxford,
  • Honorary Consultant in General Adult Psychiatry, Oxford Health NHS Foundation Trust, 
  • Chair, Oxford Neuroscience Committee 

I trained in medicine and psychiatry in Oxford and London, and was a Wellcome Trust Senior Research Fellow before being appointed to my present post in 1997. I was awarded a Chair in 2000. I head a research group investigating molecular, psychopharmacological and therapeutic aspects of mood disorders and schizophrenia – and now the psychiatric and neurological aspects of COVID-19. I have published over 340 papers (Scopus h=77), and several books, including Shorter Oxford Textbook of Psychiatry, and Schizophrenia (with Daniel Weinberger). I am a Theme Leader in the NIHR Oxford Health Biomedical Research Centre, and an investigator in the Wellcome Centre for Integrative Neuroimaging. My clinical work centres on mood disorders, and includes recruitment to and running of clinical trials. I am a Deputy Editor for Biological Psychiatry. I have served on various funding committees, chaired an NHS Research Ethics Committee, and was Treasurer for the Academic Faculty of the Royal College of Psychiatrists. I have supervised 24 PhDs. Awards include the CINP/Paul Janssen Schizophrenia Prize (1998), the British Association for Psychopharmacology Senior Clinical Prize (1999), the A.E. Bennett Award of the Society of Biological Psychiatry (2004), the Joel Elkes Research Award of the American College of Neuropsychopharmacology (2005), the CINP Lilly Clinical Neuroscience award (2010), and the ECNP Clinical Neuropsychopharmacology award (2012). I was President of the British Association for Psychopharmacology from 2014-2016.
