Dr. Alfredo Quiñones-Hinojosa received his medical degree from Harvard, where he graduated with honors. He then completed his residency in neurosurgery at the University of California, San Francisco, where he also completed a postdoctoral fellowship in developmental and stem cell biology.

Now an Associate Professor of Neurosurgery and Oncology at Johns Hopkins, Dr. Quiñones serves as the Director of the brain tumor program at the The Johns Hopkins Bayview campus. He focuses on the surgical treatment of primary and metastatic brain tumors, with an emphasis on motor and speech mapping during surgery. He is expert in treating intradural spinal tumors as well as brainstem and eloquent brain tumors in adults with the use of neurophysiological monitoring during surgery. He further specializes in the treatment of patients with pituitary tumors using a transphenoidal endonasal approach with surgical navigation and/or endoscopic techniques. He has a strong interest in treating patients with skull base tumors and the use of radiosurgery as an adjunct to the treatment of these lesions.

Dr. Quinones conducts numerous research efforts on elucidating the role of stem cells in the origin of brain tumors and the potential role stem cells can play in fighting brain cancer and regaining neurological function.

His most recent accolade was being honored with the American Association of Neurological Surgeons Ronald Bittner Award. He has also received multiple teaching awards.

Dr. Quiñones currently sees patients at The Johns Hopkins Bayview Hospital Outpatient Center on Tuesdays.
