He served time as Chair of Neurology at Barrow Neurological Institute in Phoenix, before returning to Stanford in 2000. He has had a leading role in the testing of devices that can detect or treat seizures, including deep brain stimulation, focal drug infusion, seizure notification accelerometers and biosensor. He also collaborates with laboratory researchers studying mechanisms of epilepsy. He has been named in Best Doctors of America for 16 consecutive years. He is a past-president of the American Epilepsy Society, prior Editor-in-Chief of the world's main epilepsy journal, Epilepsia, and past Editor of, the most visited website about epilepsy. He has published numerous articles and books about epilepsy.

Josef Parvizi, MD, PhD
Professor of Neurology & Neurological Sciences
Director of Stanford Program for Intractable Epilepsy

Dr. Parvizi’s clinical training is from Mayo Clinic- Rochester, BIDMC-Harvard University, and UCLA. His major interest is in the study of seizure propagation and treating patients with intractable epilepsy. His special expertise is in detecting the epileptic source in patients with uncontrolled seizures and mapping the brain circuitries that underlie development and spread of seizures. He performs functional brain mapping of the brain during epilepsy surgery evaluations. Dr. Parvizi is also the Director of the Stanford Human Intracranial Cognitive Electrophysiology Program (SHICEP), and is involved in multidisciplinary collaborative research projects with several Stanford principal investigators to understand how different parts of the human brain work and how their function may be broken during seizures.

Kevin Graber, MD
Clinical Professor of Neurology & Neurological Sciences
Director of Outpatient Epilepsy Clinic

Dr. Kevin Graber earned his MD from Indiana University in 1992 and completed his training in Neurology & Neurological Sciences at Stanford Medical Center. Dr Graber has earned prestigious research awards and has served on several national committees including the American Epilepsy Society, CURE, and Epilepsy Foundation. As a Clinician Educator, Dr. Graber provides clinical care to patients with epilepsy, and teaches fellows, residents, and medical students. Dr. Graber's research is focused on discovering how brain injuries, such as trauma, lead to epilepsy.


Lawrence Recht, MD
Professor of Neurology
Director, Adult Neuro-Oncology

Dr. Lawrence Recht received his medical degree from Columbia University College of Physicians and Surgeons in New York City. He completed his training as a Resident in Neurology at Columbia Presbyterian, Neurological Institute of New York. His interest in helping people with brain tumors led him to additional training and completion of a Fellowship in Neuro-Oncology at Memorial Sloan Kettering Cancer Institute in New York.

As an attending in Neurology with a specialty in Neuro-Oncology, Dr. Recht moved to the University of Massachusetts Medical School where he spent 19 years caring for patients and working in his research lab to try to find a cure for brain tumor. During this time Dr. Recht became convinced that it was better for patients to find out how and why a brain tumor evolved so that it could be treated earlier rather than directing his efforts toward treating the tumor after it had already caused disability.

In 2004, Dr Recht relocated to Stanford to work on furthering his research on Early Detection of Brain Tumor and to develop an expanded Adult Neuro-Oncology Program. Belief in hope and quality of life drives Dr. Recht and his team's practice of caring for patients and families with brain tumor and neurologic complications of cancer. Clinical studies are also provided and available for patients with specific conditions who are interested in adding experimental treatments to their care.

Efforts in Dr. Recht's research laboratory are directed towards applying early detection strategies to the treatment of brain tumors. In addition, other work in his laboratory is directed at reversing the damaging side effects of treatment-related brain injury.

Seema Nagpal, MD
Clinical Associate Professor of Neurology and Neurologial Sciences

Dr. Nagpal earned her medical degree at the University of Pennsylvania, completed Neurology residency at University of California, San Francisco and Neuro-Oncology fellowship at Stanford University. Dr. Nagpal is focused on developing therapy that increases both quantity and quality of life for patients with primary brain tumors. She also has a special interest in neurologic complications of systemic cancer, such as brain and leptomeningeal metastases. Dr. Nagpal’s research efforts include clinical trials in glioma and collaborative projects to identify the genetic under-pinnings of brain metastases.


Benjamin I. Chung, MD
Associate Professor of Urology

Benjamin I. Chung, MD is a Urologic Oncologist specializing in the treatment of prostate and kidney cancer. As Director of Robotic Surgery, he has one of the largest surgical experiences in robotic prostatectomy and robotic kidney surgeries in the Bay Area and his excellent outcomes have resulted in his election to Castle Connolly Top Doctors and Best Doctors in San Francisco.

Dr. Chung's research focuses upon improving outcomes of surgical management of urologic cancers and in better understanding the causative factors in the formation of these malignancies to allow for future preventative action.


Joyce Liao, MD, PhD
Associate Professor, Director of Neuro-Ophthalmology

Dr. Liao is an associate professor of ophthalmology at Stanford. She played a key role in the creation of the Stanford Center for Vision and Blindness Prevention—a group of vision scientists spanning a range of disciplines. The center’s goal is to develop practical solutions for restoring vision and precluding blindness.

Dr. Liao attended Harvard for her undergraduate studies and the University of California, San Francisco, for her MD and PhD. She completed neurology training at Stanford and neuro-ophthalmology fellowship at UCSF. She specializes in vision changes due to nervous system conditions. Common neuro-ophthalmic issues include vision loss, visual disturbances, double vision, and eye movement abnormalities.
