Dr. John W. Barnhill is DeWitt Wallace Senior Scholar, Professor of Clinical Psychiatry, and Professor of Medical Ethics at Weill Cornell Medicine.
Dr. Barnhill has maintained a private psychiatric practice throughout his career. His outpatient efforts have tended to overlap with and be informed by his clinical and academic work, described below.
Dr. Barnhill's clinical efforts have included 15 years as service chief and/or departmental vice chair for consultation-liaison psychiatry at New York Presbyterian/Weill Cornell Medicine (NYP/WCM). For five years, he directed NYP/WCM's mental health services for all house staff. He currently serves as psychiatric liaison to the kidney transplant service after having previously worked with teams from cardiology, dermatology, and rheumatology. Since 2010, he has been chief of psychiatry at the Hospital for Special Surgery.
Dr. Barnhill's scholarly efforts have focused on psychiatric assessment and treatment. It is a challenge to maintain simplicity when humans are complicated, and to develop clarity when people present with some combination of sadness, anxiety, stress, substance use, burnout, comorbid medical conditions, and patterns of interpersonal conflict. Similarly, it is a challenge to recommend the best treatment in a field with so many competing and overlapping psychotherapeutic, behavioral, and pharmacologic interventions.
Dr. Barnhill's six books include: Approach to the Psychiatric Patient, 2nd edition (2019), a text that includes over 100 authors from Weill Cornell or Columbia; Co-Occurring Mental Illness and Substance Use Disorders: A Guide to Diagnosis and Treatment, edited with Dr. Jonathan Avery (2017); DSM-5 Clinical Cases (2013); and Approach to the Psychiatric Patient (2008). These books have been translated into a total of 12 languages. He also edits the Anxiety, Stress, and Trauma section for the online Merck Manual; in 2019, his chapter received 1.7 million hits. He is currently working on an update to the DSM-5 Casebook that will accompany the revised DSM-5 in 2021.
Dr. Barnhill chairs the psychiatry department's Appointments and Promotions Committee as well as its Committee on Faculty Development. He has served on most of WCM's medical student education committees and on most of the psychiatry department's education and administrative committees. He has served on the NYP/WCM Ethics Committee since 2001. He has chaired the WCM General Faculty Council (the representative body for all WCM faculty) and the Payne Whitney Faculty Council (which represents all of the psychiatry faculty).
Outside of NYP/WCM, Dr. Barnhill chairs the Ethics Committee for the Psychoanalytic Center at Columbia University, where he teaches the Ethics course to advanced candidates. Between 2013 and 2019, Dr. Barnhill served on the editorial board for books published by the the American Psychiatric Association.
Since 2015, Dr. Barnhill has directed the psychiatry section of the annual Salzburg Weill Cornell Seminars, which are focused on the continuing education of young psychiatrists from developing countries, particularly in Eastern Europe. He has served on the WCM Faculty Committee for the Weill Bugando Medical College in Mwanza, Tanzania and on the International Psychoanalytic Association's and the American Psychiatric Association's Committees to the United Nations and on the United Nations Commission on the Status of Women.
Dr. Barnhill has lectured or consulted throughout the country, as well as the Middle East, Africa, Europe, and Asia.
