Additional Information

Dr. Al Powers is an Associate Professor in the Department of Psychiatry at Yale School of Medicine and serves as Medical Director and Associate Director of the renowned PRIME Psychosis Risk Clinic at Yale. He earned his BA from Yale University (2004) and both his MD and PhD from Vanderbilt University School of Medicine (2012). Following graduation, Dr. Powers completed a research-track psychiatric residency at Yale University School of Medicine, serving as Chief Resident in the Neuroscience Research Training Program. Dr. Powers specializes in treating individuals experiencing early psychosis symptoms while employing computational approaches to understand how sensory systems produce hallucinations and other psychotic symptoms. His laboratory utilizes diverse methodologies including computational modeling, functional neuroimaging, electrophysiology, psychophysics, and qualitative analysis to understand how psychotic experiences emerge. His research encompasses hallucinations, delusions, schizophrenia spectrum disorders, psychosis risk assessment, and the computational signatures underlying these conditions. Dr. Powers has made foundational contributions to understanding hallucinations as perceptual phenomena, including landmark research published in Science demonstrating that hallucinations result from overweighting of perceptual priors. His work has developed comprehensive computational models explaining the development and evolution of psychotic symptoms from their earliest emergence. Dr. Powers' scholarly work has been cited over 4,400 times in peer-reviewed literature and he has received numerous awards for both his clinical and research work. Dr. Powers brings unparalleled expertise in matters involving: - Psychotic disorders and schizophrenia spectrum conditions - Hallucinations and delusions (assessment, mechanisms, and trajectories) - Early psychosis identification and risk assessment - Psychiatric diagnosis and differential diagnosis - Treatment standards for psychotic disorders - Neurobiological basis of psychiatric symptoms - Computational psychiatry and precision medicine approaches His dual expertise as both a practicing clinician treating patients with psychosis and an internationally recognized researcher positions him to provide authoritative testimony on psychiatric causation, diagnosis, prognosis, and standards of care in complex legal matters.
