Ryan Sultan, MD is an Assistant Professor of Clinical Psychiatry at Columbia University Irving Medical Center and New York-Presbyterian Hospital, with affiliations in the Department of Biomedical Informatics. He directs the Sultan Lab for Mental Health Informatics, where his research applies data science, large-scale health analytics, and artificial intelligence to pressing questions in adolescent mental health.

Dr. Sultan’s work leverages national datasets — including IQVIA, IBM MarketScan, and Medicaid claims — encompassing cohorts of over 400,000 patients to identify population-level patterns in psychotropic prescribing, substance use risk, and treatment outcomes. His findings have been published in *JAMA Network Open*, *JAMA Psychiatry*, and *Pediatrics*. He is a recipient of the NIDA K12 Clinical Scientist Career Development Award.

His current research integrates NLP and large language models into clinical psychiatric practice, including the development of AI-enabled digital therapeutics for adolescent cannabis use disorder. He has also contributed to the emerging field of AI behavioral science — applying clinical psychiatric methodology to characterize and intervene on behavioral phenomena in large language models, including sycophancy, confabulation, and identity instability.

Dr. Sultan is the founder of Integrative Psych, one of the leading integrative psychiatry practices in the United States, and the creator of PsychNearMe.org, a data-driven psychiatrist finder platform. He is double board-certified in adult and child/adolescent psychiatry.
