About Me

I am a board-certified neurosurgeon who has completed additional fellowship training in brain tumor surgery. As a member of Memorial Sloan Kettering’s Brain Tumor Center, I provide care for patients with primary brain tumors (such as glioblastomas and astrocytomas), tumors that line the skull (meningiomas), and tumors that have spread to the brain from other parts of the body (brain metastases).

I also specialize in “mapping” of the brain during surgery to identify vital areas that control language, movement, and memory. Such mapping allows surgeons to remove tumors more precisely while sparing as much tissue as possible near these highly functional areas of the brain.

I also treat patients with pituitary tumors and other sellar and parasellar tumors. To help meet the needs of these patients, I established the Pituitary and Skull Based Tumor Center at Memorial Sloan Kettering.

Unique to New York City, the Pituitary and Skull Based Tumor Center offers specialized multidisciplinary care and expertise in surgery, endocrinology, and neuro-ophthalmology for patients with these types of tumors. Patients with pituitary tumors benefit from the use of MRI during surgery that enables us to perform safer, more extensive surgeries.

I am also a neuroscientist. In my research laboratory at Memorial Hospital, I am studying the potential use of neural and pluripotent stem cells to repair brain tissue following injury or disease.

Clinical Trials

As home to one of the world’s top cancer research centers, Memorial Sloan Kettering is typically involved in more than 900 clinical trials at a given time. Currently, clinical trials focused on the conditions I treat are enrolling new patients.

Most major health insurers offer plans that include MSK as one of their in-network providers. If MSK is in-network, it means all our doctors are too. Medicaid and New York State Medicare also provide benefits for care at MSK.
