    Collapse Overview
    Dr. Powell received her BA degree with honors in Psychology from the University of North Carolina at Chapel Hill and her PhD in Behavioral Neuroscience from the University of Florida. She completed her postdoctoral training in psychopharmacology in the UCSD Psychiatry Department. She is currently a Professor in the Department of Psychiatry at UCSD and a Research Scientist at the Veterans Affairs San Diego Healthcare System. She has been the principal investigator on research awards from NIMH, NIEHS, and NARSAD. Dr. Powell’s career has focused on the translational interface of animal and human neurodevelopmental research. Her research examines early risk factors contributing to neurodevelopmental disorders such as schizophrenia and autism. Studies seek to determine the effects of environmental exposures and their combination with genetic susceptibility on genome-wide DNA methylation and behavior in mice. Her research also involves basic studies on the behavioral effects of hallucinogens in rodents with the hope that these models will inform us about psychosis in humans and lead to development of novel therapeutics for individuals with schizophrenia.
