Biography
Andrew Sheldon received his undergraduate training at the University of California Berkley with a concentration in Physics before attending the University of Wisconsin School of Medicine and Public Health for his M.D. PhD where he applied computational methods and modeling to neuroimaging data to better understand the interactions between attention and working memory. After completing this work in 2019, he was accepted into the Solnit integrated research track combined residency and fellowship in adult and child psychiatry, where he currently works in the Al Powers lab using computational modeling approaches to understand the neural mechanisms underlying hallucinations, in addition to his clinical psychiatry duties caring for children and adolescents through the Yale Child Study Center and Yale New Haven Children's hospital.
