Antonio Meola, MD, PhD
Clinical Assistant Professor, Neurosurgery
Clinical Assistant Professor (By courtesy), Otolaryngology (Head and Neck Surgery)
BioAntonio Meola M.D. Ph.D graduated Summa cum Laude and Research Honors at the University of Pisa, Italy, in 2008, and completed his residency training in Neurosurgery at the same Institution in July 2015. Dr Meola attended a Ph.D. program at the University of Florence, Italy, where he discussed a doctoral thesis entitled "A New Head-Mounted Display-based Augmented Reality System in Neurosurgical Oncology: a study on phantom".
Since 2/2014 to 1/2015 Dr Meola completed a Research Fellowship in Neurosurgical anatomy at the University of Pittsburgh Medical Center (UPMC), under the Direction of Dr. Juan C. Fernandez-Miranda. The main focus of his research was the surgical neuroanatomy of the white matter tracts of the human brain.
Since 7/2015 to 6/2016 Dr Meola served as Clinical Fellow in Image-Guided Neurosurgery at the Brigham and Women's Hospital, Harvard Medical School, in Boston, MA (Director: Dr. Alexandra J. Golby M.D.). During the fellowship, he focused on the clinical application and integration of advanced imaging techniques, including intraoperative-MRI, intraoperative US, functional MRI, tractography.
Since 7/2016 to 6/2017 Dr Meola completed a Neurosurgical Oncology Fellowship at the Cleveland Clinic in Cleveland, OH, devoting his efforts to minimally-invasive neurosurgical techniques, such as Laser interstitial Thermal Therapy (LITT) and stereotactic radiosurgery (Gamma Knife), as well as to awake neurosurgery.
Starting 7/2017, Dr Meola joined the Department of Neurosurgery at Stanford. Dr. Meola mainly focuses on conventional and innovative treatments for brain and skull base tumors, including both surgery and stereotactic radiosurgery (CyberKnife).
