McGeary’s research focuses on the intersection of neuroscience, genetics, and clinical psychology to inform questions of etiology and treatment. He directs a molecular lab located at the Providence VA Medical Center where he is also a staff psychologist treating Veterans with substance use disorders. He actively collaborates on 65+ research projects with investigators at Brown, affiliated hospitals and collaborating institutions and consortia (e.g., Million Veteran Program) around the country. Dr. McGeary’s research interests include: 1) genetic and epigenetic variation associated with psychiatric and behavioral phenotypes (and recently with phenotypes of interest to researchers in Dermatology, Surgery, Infectious Disease, Neuroscience, Computer science, Gerontology, and Public Health); 2) the role of sleep in suicide, addiction, and other psychopathology; and 3) the use of neurostimulation for treatment of addiction.
