Dr. Henry Brem is the Harvey Cushing Professor of Neurosurgery at The Johns Hopkins University, Chairman of the Department of Neurosurgery, and Neurosurgeon-in-Chief. He also is a professor of Oncology, Ophthalmology, and Biomedical Engineering. Dr. Brem has developed new tools and techniques that have changed the field of neurosurgery. He carried out the pivotal clinical study that introduced navigational imaging into the neurosurgical suite. His work led to the FDA's approval of the first image guidance computer system for intraoperative localization of tumors. Furthermore, he has changed the surgical armamentarium against brain tumors by inventing and developing Gliadel® wafers to intraoperatively deliver chemotherapy to brain tumors. His work has shown that surgeons can accurately deliver potent therapies directly at the tumor site.
