    Collapse overview
    Xenos Mason M.D. is a neurologist and movement disorders specialist, with special interest and expertise in the use of Deep Brain Stimulation (DBS) for the treatment of movement disorders. His current research focuses on procedural therapies for movement disorders, in particular DBS. In collaboration with the USC Laboratory for Neuroimaging (LONI), Dr. Mason is studying connectomic biomarkers of DBS efficacy for Dystonia and other movement disorders. He is interested in the development of novel neuroimaging and neurophysiologic biomarkers to improve the delivery of DBS therapy, and on novel treatments for Musician's Dystonia and other forms of occupational Dystonia. Dr. Mason is also leading development of the multidisciplinary USC Musician's Neurology Clinic.

    Dr. Mason completed his medical training at Harvard Medical School, Massachusetts General Hospital, Brigham and Women's Hospital, and UCLA. He undertook a research fellowship with the Howard Hughes Medical Institute and training in Clinical/Translational Research with the UCLA-CTSI and SC-CTSI. He joined the USC faculty in the departments of Neurological Surgery and Neurology in 2021.
