Born in 1960 in Utrecht, Jim van Os is a Dutch psychiatrist and epidemiologist whose academic career has centered on the critique and reconstruction of psychiatric classification systems. Throughout his tenure at institutions including Maastricht University and King's College London, he has advocated for shifting clinical focus away from static diagnostic labels toward a dynamic psychosis spectrum model.
Academic and Clinical Training
Van Os completed his medical education at the University of Amsterdam. His clinical and research training spanned multiple international locations, including Jakarta, Casablanca, Bordeaux, and London. He pursued specialized studies in epidemiology at the London School of Hygiene and Tropical Medicine. Throughout his career, he has held significant academic and administrative positions, serving as a professor at both Maastricht University and King's College London, and currently functioning as the medical manager of the Brain Center at University Medical Center Utrecht.

In 2009, Van Os initiated a sustained campaign to retire the clinical diagnosis of schizophrenia. He argued that the label lacks scientific validity and encourages a fundamental attribution error, complicating communication between clinicians and patients. He suggested that the term should be replaced with a broader syndromal definition, aligning with theories of aberrant salience regulation. His publications on the subject include an editorial in the BMJ in 2016 and subsequent papers in Psychological Medicine and Frontiers in Psychiatry that outline the transition from the traditional diagnostic concept to a psychosis spectrum model.
Influence and Recognition
Van Os has contributed to global psychiatric standards, including service on the psychosis group for the DSM-5 Task Force. His research has earned him a place on the Thomson Reuters Web of Science list of influential scientific minds since 2014. He holds membership in the Royal Netherlands Academy of Arts and Sciences and the Koninklijke Hollandsche Maatschappij der Wetenschappen. In 2023, the Schizophrenia International Research Society awarded him its Lifetime Achievement Award.
Mental Health Ecosystems
Beyond traditional clinical research, Van Os has collaborated with colleague Philippe Delespaul to implement social trials aimed at transforming mental health services. This work is grounded in the concept of a Mental Health Ecosystem, an approach documented in his co-authored books, including We zijn God niet and Kopzorgen. Psychose begrijpen in 33 vragen. His efforts in this field emphasize patient-friendly terminology and evidence-based organizational principles for mental health care.
