Dr. Daniel P. Perl was born and raised in New York City and received his BA and MD degrees from Columbia College and the State University of New York. He then took postgraduate training in anatomic pathology and neuropathology at Yale University, following which he served for two years as a pathologist in the US Public Health Service, stationed at the Centers for Disease Control in Atlanta, Georgia. In subsequent years he served on the faculty of the Brown University Medical School and then the University of Vermont College of Medicine. In 1986, Dr. Perl joined the Mount Sinai School of Medicine in New York, where for 24 years he served as Director of the Neuropathology Division and was Professor of Pathology, Psychiatry and Neurosciences.
Dr. Perl is highly regarded for his work on various aspects of the neuropathology of age-related neurodegenerative disorders, especially the role of environmental factors in their induction. He is the leading authority on the pathology of the fascinating complex of neurodegenerative disorders occurring among the native population living on Guam. Prior to coming to Uniformed Services University of the Health Sciences, his research had been continually funded by the National Institutes of Health for 32 years. Dr. Perl has won numerous awards for his research as well as his role as a medical educator.
In September, 2010, Professor Perl left Mount Sinai to join the faculty of the Department of Defense’s Uniformed Services University of the Health Sciences, F. Edward Hébert School of Medicine, in Bethesda, MD. In conjunction with the congressionally mandated Center for Neuroscience and Regenerative Medicine, he has established a state-of-the-art neuropathology laboratory dedicated to research on the acute and long-term effects of traumatic brain injury (TBI) and PTSD among military personnel.
