Dr. Marshall received his undergraduate and medical degree from Boston University. He then completed a neurology residency at the University of Pittsburgh, followed by a dementia and behavioral neuroscience fellowship at the University of California, Los Angeles. Dr. Marshall is board certified in Neurology. He is currently the Director of Clinical Trials at the Center for Alzheimer Research and Treatment at Brigham and Women’s Hospital; Associate Neurologist at Brigham and Women’s Hospital; Assistant in Neurology at Massachusetts General Hospital; and Associate Professor of Neurology at Harvard Medical School.

Since 2004, Dr. Marshall has focused on improving the clinical care of patients with Alzheimer’s disease (AD) and related conditions, in conjunction with clinical research in AD. Since 2007, he has been site principal investigator for 14 clinical trials and 4 observational imaging studies in AD such as the Alzheimer’s Disease Neuroimaging Initiative (ADNI) and the Anti-Amyloid Treatment in Asymptomatic Alzheimer’s Disease (A4) trial. His NIH-funded research has focused on clinical correlates of instrumental activities of daily living and neuropsychiatric symptoms with amyloid, tau, and FDG PET, and structural and resting-state functional MRI across the early AD spectrum. More recently, Dr. Marshall has been developing novel sensitive performance-based instrumental activities of daily living tests for early-stage AD.
