Dr. Alfredo Quiñones-Hinojosa is an Associate Professor of Neurosurgery and Oncology, Neuroscience and Cellular and Molecular Medicine at Johns Hopkins in Baltimore, Maryland. He serves as the director of the Brain Tumor Surgery Program at the Johns Hopkins Bayview Campus.  Dr. Quiñones focuses on the surgical treatment of primary and metastatic brain tumors, with an emphasis on motor and speech mapping during surgery. He is an 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. Quiñones 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.  In addition to leading the Brain Tumor Stem Cell Laboratory, he also heads the Neuro-Oncology Surgical Outcomes Research Laboratory where he is working to improve patient safety and maximize the efficacy of current treatment paradigms for patients with brain tumors.

Most recently, Dr. Quiñones was honored with a grant from the National Institute of Health for his work with stem cells and cancer. His awards include a $450,000 Howard Hughes Medical Institute Physician-Scientist Early Career Award as well as being named one of the 100 most influential Hispanics in 2008. Dr. Quinones was also awarded the Nickens Faculty Fellowship from the Association of American Medical Colleges, recognized for leadership in addressing inequities minorities face in medical education and health care.

Dr. Quiñones received a medical degree from Harvard University, where he graduated cum laude. He went on to complete his residency in neurosurgery at the University of California, San Francisco, where he also completed a postdoctoral fellowship in developmental and stem cell biology.

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