Keith G. Davies, MD

Associate Professor, Neurosurgery

Keith Davies
88 E. Newton St Newton Pavilion


Dr Davies graduated in medicine from the University of Wales in Cardiff in the United Kingdom. He trained in surgery and became a fellow of the Royal College of Surgeons of England in 1981. He subsequently trained in Neurosurgery in Sheffield and Cardiff in the United Kingdom and at the University of Minnesota. He was accredited in Neurosurgery by the Royal College of Surgeons of England in 1989. In 1994 he joined Semmes-Murphey Clinic in Memphis where he was the Surgical Director of the Epi-Care comprehensive epilepsy center, and Associate Professor of Neurosurgery at the University of Tennessee.

He worked in private neurosurgery practice in St Paul, Minnesota from 2000 to 2006, and joined the medical staff at Boston University and Boston Medical Center at the end of 2006.

Dr Davies performs surgery for placement of deep brain stimulators in patients with Parkinson’s disease and other movement disorders. This involves stereotactic placement of the electrodes and implantation of the generators. He also undertakes general neurosurgery procedures and has an interest in the surgical treatment of epilepsy as well as spinal cord stimulation for the treatment of chronic pain.

Dr Davies has conducted and published clinical research into deep brain stimulation. He has also published research into the surgical treatment of intractable epilepsy. He is involved in teaching of medical students and residents, and is a member of the Congress of Neurological Surgeons and of the American Epilepsy Society.
