The Stanford Neuro-Oncology Program Team

Adult Neuro-Oncologists

Lawrence Recht, MD
Professor of Neurology and Neurological Sciences
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

Adult Neuro-Oncology Fellows

Chirag Patel, MD, PhD

Dr. Patel graduated with BS/MSE degrees in biomedical engineering from Johns Hopkins University and MD/PhD degrees from the University of Texas Medical School at Houston. During his adult neurology residency training at UCLA, he was awarded a NINDS Research Education Grant (R25) to study the role of 18F-DOPA PET imaging in the diagnosis of and treatment planning for glioma. As a neuro-oncology research fellow at Stanford, he is investigating multimodal imaging techniques in glioma diagnosis and therapy in the laboratory of Dr. Sanjiv Sam Gambhir. As a neuro-oncology clinical fellow, he plans to translate research findings from the lab to help patients suffering from brain tumors.
