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. He is board certified in Neurology. He is currently the Associate Medical 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. Over the past 16 years, he has focused on improving the clinical care of patients with Alzheimer’s disease (AD) and related conditions, in conjunction with clinical research in AD. Over the past 13 years, he has been site principal investigator for 13 clinical trials and 4 observational imaging studies in AD and is currently the site principal investigator for the Alzheimer’s Disease Neuroimaging Initiative (ADNI) 3, DoD-ADNI, and the Anti-Amyloid Treatment in Asymptomatic Alzheimer’s Disease (A4) trial. His research has focused on clinical correlates of instrumental activities of daily living and neuropsychiatric symptoms with amyloid, tau, and FDG PET, structural and resting-state functional MRI, and CSF biomarkers across the early AD spectrum. More recently, he has been developing novel sensitive performance-based instrumental activities of daily living tests for early-stage AD.
