About the Division

The experts at the Division of Neuro-Oncology are transforming the way brain and spine tumors are prevented, detected and treated. We deliver a full range of research-based, interdisciplinary and comprehensive care for patients with all forms of brain and spine cancer. Our subspecialists are world-renowned authorities in neuro-oncology, surgery, radiology and research who work together to devise optimal treatment plans for each patient’s biologically unique cancer. Innovative clinical trials and groundbreaking research often lead to the most advanced treatments offered anywhere. We benefit from a wealth of resources available to us as part of an academic medical center, a National Cancer Institute (NCI)-designated Comprehensive Cancer Center and a freestanding cancer hospital, all located on the main campus of one of the nation’s largest universities.

GiglioPierreWelcome from Division Director,
Pierre Giglio, MD

Treating nervous system cancers requires a management approach that includes not just one physician but a team of specialists, including neurosurgeons, radiation oncologists, pathologists, neuroimaging specialists and more working in a collaborative environment. Our team uses innovative technologies to perform genetic and molecular analysis of brain and other central nervous system tumors. The combination of our expertise and technological capabilities means patients receive individualized and targeted treatment plans for their specific needs. Our residency and fellowship programs are competitive, in demand, and provide opportunities for lasting and meaningful research.
