Her research examines the effects of age, sex, neurological disease, head injury, and experience (elite versus non-elite athletes) on the brain's control of complex movement. Dr. Sergio works with a wide range of adult populations, including NHL draft prospects and Alzheimer's disease patients, using behavioural and brain imaging techniques.
