Alexis Demopoulos, MD joined the North Shore-LIJ Health System in 2005 as the Director of Neuro-Oncology at North-Shore University Hospital and Long Island Jewish Medical Center. Since that time, the program has grown to cover the entire NSLIJ health system, with centers of excellence devoted to the care of the Brain Tumor Patient at Lenox Hill Hospital, NSUH - Manhasset, and Staten Island University Hospital.

Dr. Demopoulos applies his broad experience in the diagnosis and treatment of primary brain tumors and cancer s effects on the brain, spine, and peripheral nerves to the care of patients with primary brain tumors or cancers that have spread from elsewhere in the body to affect the brain. His special interests include evaluating new therapies for gliomas, bench-to-bedside research exploring how brain tumors grow, and systemic and intrathecal chemotherapy for other cancers afflicting the brain.

Dr. Demopoulos received his MD from Northwestern University in Chicago and trained in Neurology at New York Presbyterian Hospital (Cornell) in Manhattan. He completed research and clinical fellowships at Memorial Sloan Kettering Cancer Center (MSKCC) in 1997 and 2001-2003 before joining the Attending staff there until 2005. He received the Charles H. Revson Fellowship for Biomedical Research for the study of therapeutic glioma vaccines, a new approach to cancer that uses the body s own immune system to fight disease.

Dr. Demopoulos is Board Certified in Neurology and Psychiatry (Neurology). He is also Board Certified in Neuro-Oncology by the United Council for Neurologic Subspecialties. He is a member of the American Academy of Neurologists (AAN), the American Society for Clinical Oncoloy (ASCO), and the Society for Neuro-Oncology (SNO).
