Golfo Tzilos Adjunct Assistant Professor of Psychiatry and Human Behavior, Adjunct Assistant Professor of Behavioral and Social Sciences

Golfo Tzilos is a licensed clinical psychologist and an Assistant Professor (Research) in the Departments of Psychiatry & Human Behavior and Behavioral & Social Sciences at Brown University. She received a Ph.D. in clinical psychology from Wayne State University in Detroit, MI, completed a predoctoral internship at Brown Medical School, and a postdoctoral fellowship at the Brown Center for Alcohol and Addiction Studies. Her primary research interests are in computer-delivered approaches to intervene with vulnerable populations, including women and emerging adults at risk for HIV/STIs, alcohol/drug use, and intimate partner violence. She is currently a PI or Co-I on three NIH studies to develop and test computer-based interventions that target health risks in pregnant/perinatal women and in foster youth.
