Staci Gruber, PhD

Contributor

Dr. Staci Gruber received her PhD from Tufts University, and is currently an associate professor of psychiatry at Harvard Medical School and the director of the Cognitive and Clinical Neuroimaging Core at McLean Hospital. Over the last several decades, her research has focused on the application of neurocognitive models and brain imaging to characterize risk factors for substance abuse and psychiatric conditions.
