Associate Research Scientist in Psychiatry
Biography
Dr. Grazioplene's research examines associations between neural phenotypes and human individual differences, with a focus on understanding how variation in neural features supports adaptive levels of personality function, and how these neural characteristics may become dysregulated in the context of psychopathology. She is particularly interested in examining neural features linked to psychosis-proneness and subclinical expressions of risk for obsessive-compulsive disorder. She received her Ph.D. in Psychology from the University of Minnesota in the Personality, Individual Differences, and Behavioral Genetics program.
