Dr. Sabina Berretta

Sabina Berretta, MD -- Director

Dr. Berretta is the director of the Harvard Brain Tissue Resource Center (HBTRC) and the Translational Neuroscience Laboratory at McLean Hospital, as well as an associate professor of psychiatry (neuroscience) at Harvard Medical School. She is responsible for the overall management of the HBTRC, from its mission and vision to its daily procedures. She works closely with leadership at the National Institutes of Health (NIH) NeuroBioBank (NBB) leadership, private foundations and investigators who are interested in requesting tissue from the HBTRC. She also participates in community education activities and family advocacy meetings. She is part of the HBTRC Consensus Diagnosis Team, which conducts thorough analyses of HBTRC donors to rebuild a full picture of their health conditions. Dr. Berretta's research focuses on the pathophysiology of psychiatric disorders, with a particular emphasis on the role of the extracellular matrix in brain disorders and the neural circuits involved in regulating emotion and psychiatric symptoms. She strongly believes that research on brain disorders is not only essential to our knowledge of their pathology and advancement of new therapeutic approaches, but also to our understanding of people impacted by these disorders. Such understanding is critical to combat stigmatization and its socio-economical and legal implications.
