Dr. Hallett is an NIH Distinguished Investigator and the Chief of the Human Motor Control Section, National Institute of Neurological Disorders and Stroke, NIH, Bethesda. He trained at Harvard Medical School, NIH, Massachusetts General Hospital and the Institute of Psychiatry in London. From 1976 to 1984, Dr. Hallett was the Chief of the Clinical Neurophysiology Laboratory at the Brigham and Women's Hospital and rose to Associate Professor of Neurology at Harvard Medical School. From 1984, he has been at the National Institute of Neurological Disorders and Stroke where he also served as Clinical Director of NINDS until July 2000. He is currently past President of the International Federation of Clinical Neurophysiology and the President of the newly founded Functional Neurological Disorder Society. Dr. Hallett is also remote past President of the Movement Disorder Society and past Editor-in-Chief of Clinical Neurophysiology. He has won many awards including, in October 2019, the World Federation of Neurology Medal for Contributions to Neuroscience. His work mainly deals with principles of motor control and the pathophysiology of movement disorders. The work in his Section has a major focus on Functional Movement Disorders.
