Vanderbilt Department of Neurology

Faculty By Divisions

Thomas L. Davis, M.D.

Professor of Neurology


Dr. Davis received his Bachelor’s degree from the College of Wooster, Wooster, Ohio, in 1981 and his M.D. from the University of Mississippi School of Medicine, Jackson, Miss., in 1985. He stayed in Jackson for a year of internship, then came to Vanderbilt’s Neurology department for his residency (1986-89). Davis left Vanderbilt for a two-year post-doctoral fellowship in Neuropharmacology at the National Institute of Neurological Disease and Stroke in Bethesda, Maryland. He returned to Vanderbilt to join the faculty in the Department of Neurology in 1991.

Davis has been the recipient of a number of honors, including being named Phi Beta Kappa in 1981, receiving the Sandoz Award in 1989, and being named to the list of Best Doctors in America: Midwest Region in 1996.

In addition to maintaining his clinical research activities and teaching responsibilities, he is currently director of the Division of Movement Disorders, director of the General Clinical Research Center (GCRC) Core Laboratory,an attending physician at Vanderbilt University Medical Center, a staff neurologist at the Nashville Veterans Administration Hospital, and neurological consultant at Vanderbilt-Stallworth Rehabilitation Hospital and Nashville General Hospital.

Davis is a member of the American Academy of Neurology, the American Autonomic Society, The Movement Disorder Society, and the American Society of Experimental Neurotherapeutics.


My research is patient oriented and involves primarily various aspects of Parkinson's disease including: markers of disease progression, pathophysiology of motor fluctuations, and autonomic failure in Parkinson's disease. The Division of Movement Disorders is actively involved with clinical trials in neuroprotection in Parkinson's disease and treatments of spasticity and dystonia.
