Ray M. Chu, MD

Neurosurgeon, Brain Tumor Center

Ray M. Chu, MD is a board certified attending neurosurgeon in the Department of Neurosurgery at Cedars-Sinai Medical Center. His interests include brain and spinal cord tumors, neuroendoscopy, spinal disorders, peripheral nerve and brachial plexus disorders, hydrocephalus, vagus nerve stimulation and surgery for epilepsy.

Cedars-Sinai is proud to be one of the few hospitals in the country with a very current intraoperative MRI, and Dr. Chu has taken the lead in utilizing this new technology. With this device, a brain tumor surgeon can actually take an MRI of the surgical site in the middle of surgery, which can contribute to a safer tumor surgery and can maximize the extent of tumor resection at surgery.

Dr. Chu has extensive experience in radiosurgery, including use of the gamma knife system and spinal radiosurgery. He also is well-versed in hydrocephalus including the use of endoscopic third ventriculostomy (ETV), a hydrocephalus procedure which can obviate the need for a shunt. He also has extensive experience in normal pressure hydrocephalus (NPH), one of the "reversible" causes of dementia, and the use of programmable ventriculoperitoneal shunts.

Over the course of Dr. Chu's career, his research has included malignant brain tumors, a neuroprotective compound in stroke, high-field magnetic resonance imaging (MRI), sleep disorders and macular degeneration. His current research interests include new technologies in neurosurgery and clinical trials for brain tumors, including brain tumor vaccine protocols.  He has made presentations at numerous professional conferences across the United States, such as the Congress of Neurological Surgeons, the North American Skull Base Society and the Minnesota Surgical Society. He is a member of the American Association of Neurological Surgeons, Congress of Neurological Surgeons, and the Society for Neuro-Oncology as well as a diplomate of the American Board of Neurological Surgery.

Dr. Chu has written numerous articles for peer-reviewed publications, including Neurosurgery, Pediatric Neurosurgery, Neurosurgical Focus, Techniques in Neurosurgery and Neuroimaging Clinics of North America. He also co-authored a chapter for the Textbook of Neurological Surgery: Principles and Practice and wrote a chapter on surgical management of high grade gliomas. In 2007, he was listed as one of "America's Top Surgeons" by the Consumers' Research Council of America.  

Dr. Chu earned his bachelor’s degree in biological sciences from Stanford University and his medical degree from the University of California at San Diego. Following this, he completed a neurosurgery residency at the University of Minnesota.
