Our Team
Gary K. Steinberg, MD, PhDBernard and Ronni Lacroute-William Randolph Hearst
Professor of Neurosurgery and the Neurosciences
Director, Stanford Institute for Neuro-Innovation and Translational Neurosciences
Chairman, Department of Neurosurgery
Co-Director, Stanford Stroke Center
As founder and Co-Director of the Stanford Stroke Center, Dr. Steinberg has practiced medicine at Stanford for more than 20 years. He has pioneered stereotactic microsurgical techniques to repair intracranial vascular malformations and certain aneurysms that were previously considered untreatable. He has also refined revascularization techniques for patients with cerebrovascular occlusions, as well as moyamoya disease.
Dr. Steinberg is currently investigating an innovative approach to improve stroke recovery by transplanting neural cells into damaged brain tissue.
Michael Marks, MDProfessor of Radiology and (by courtesy) Neurosurgery
Director, Stanford Stroke Center Neuroradiology and Interventional Neuroradiology
As Director of Neuroradiology for the Stanford Stroke Center, Dr. Marks oversees the endovascular treatment program. Using catheter-based approaches, he has pioneered techniques to effectively cure cerebral aneurysms by inserting platinum coils and using special glues to obliterate arteriovenous malformations. Dr. Marks has also employed endovascular techniques to treat ischemic cerebrovascular disorders. He has a broad experience with cerebral angioplasty, and he is currently developing a new laser therapy for vaporizing intracranial thrombi.
Robert Dodd, MD, PhDAssistant Professor of Neurosurgery and Radiology
Dr. Dodd received his medical degree from the Stanford University School of Medicine, where he also earned a PhD in Neurosciences from the Department of Neurobiology. His neurosurgery training also took place at Stanford, where he recently completed an endovascular fellowship. His research interests have been in cerebral blood vessel reactivity and stroke. Dr. Dodd's clinical interests include endovascular and microsurgical treatment of intracranial aneurysms and arteriovenous malformations; percutaneous and surgical interventions for both extracranial and intracranial carotid artery occlusive disease; and minimally invasive neurosurgery though the use of neuroendoscopy and keyhole approaches.
Huy Do, MDAssociate Professor of Radiology and (by courtesy) Neurosurgery
Dr. Do employs interventional neuroradiologic approaches to treat both ischemic and hemorrhagic cerebrovascular disorders. He has developed expertise in cerebral angioplasty and intra-arterial thrombolysis,as well as the treatment of aneurysms, arteriovenous malformations and cerebral vasospasm.
Dr. Do's current research focuses on evaluation of neuroprotectants for ischemic strokes, development of novel laser microdevices for emulsification of intracranial clots, stenting of carotid and vertebral arterial stenoses, evaluation of new liquid embolic agents for arteriovenous malformations, neuroimaging of strokes, vascular malformations, aneurysms using advanced MRI techniques, and treatment of painful compression fractures with acrylic cement.
Teresa Bell-Stephens, CNRNTeresa has worked with the Department since 1990. She has an extensive background in critical care, and her current focus is on coordinating the cerebrovascular surgery program, with an emphasis on moyamoya disease, vascular malformations and intracranial aneurysms. Teresa is a frequent lecturer for Bay Area nurses on various neuroscience nursing topics and has presented many papers at the annual meetings of the American Association of Neuroscience Nurses (AANN) and the World Federation of Neuroscience Nurses (WFNN). She has published peer reviewed neuroscience nursing articles in various journals.
Joli Vavao, MSN, ACNP, CNRN
Joli joined the Neurosurgical team in 2004. She obtained her masters degree as an acute care nurse practitioner from the University of California, Los Angeles. She has worked as a nurse for over 13 years specializing in neurosurgery and stroke neurology. She has received national certification in neuroscience nursing. She plays an active role coordinating the care of cerebrovascular patients in both an inpatient and outpatient setting. She participates in lectures to hospital staff and local health care professionals regarding the care of neuroscience patients.
Mary L. Marcellus, RN
Originally from Connecticut, Mary came to Stanford in 1980. She began as a staff nurse in the ICU and then went on to become an Assistant Nurse Manager for several years before taking on the role of Interventional Neuroradiology Nurse Coordinator in 1993. She has lectured on various cerebrovascular topics as well as published several articles in her area of expertise. Patient advocacy remains the most important part of her daily patient care responsibilities.
Carol A. Barch, MN, CRNP
Carol is a Nurse Practitioner, specializing in strokes. She received her Bachelor's degree in Nursing from Wayne State University in Detroit, and a master and post-master's nursing degree from Emory University in Atlanta. She has received national certification in critical care nursing, neuroscience nursing and as a family nurse practitioner. Carol's work in stroke began as a clinical coordinator for the National Institutes of Health, National Institute of Neurological Disorders and Stroke t-PA stroke study. Since then she has worked as an advanced practice nurse and traveled throughout the United States as a consultant for the National Stroke Association. Her work also included various publications on topics related to acute stroke and she is an expert on stroke prevention.
JoAnn Ceranski, Transcranial Doppler Technologist
JoAnn has worked at Stanford for 25 years doing various forms of neurodiagnostic testing, including transcranial Doppler (TCD). She routinely sees our moyamoya patients daily for TCDs while they are in the hospital.
