Amy Byers, PhD, MPH

Professor In Residence

Dr. Byers is Professor of Psychiatry & Behavioral Sciences with a joint appointment in the Department of Medicine, Division of Geriatrics. She is an epidemiologist with a background in aging research, methods, and biostatistics. Her research focuses on the epidemiology of late-life mental health and employs advanced epidemiological and biostatistical techniques to determine the incidence, prevalence, risk factors, and outcomes of late-life mental health disorders with the objective of reducing the burden of these disorders by informing long-term clinical care. Dr.
