Wade Berrettini, MD, PhD is the Karl E. Rickels Professor of Psychiatry at the University of Pennsylvania Perelman School of Medicine. He earned his MD (1977) and PhD (Pharmacology, 1979) from Thomas Jefferson University. After Psychiatry residency training, he studied genetics of behavioral disorders at the National Institute of Mental Health for 10 years. Since 1997, Dr. Berrettini has served as the Director of the Center for Neurobiology and Behavior, a group of interdisciplinary scientists studying genetic and biologic influences on brain disorders. The author of more than 400 peer-reviewed publications, his research interests include genetics, pharmacogenetics and medical treatment of addictions, mood disorders, schizophrenia, and epilepsy. The Berrettini lab is currently studying single cell transcriptomics in neurons and glia as potential causative factors in risk for addictions, psychotic illnesses, and mood disorders. Another focus of the lab is a pharmacogenetic study of buprenorphine and methadone treatment for opioid use disorder.
