Bruce R. Troen, MD, ASGF

Professor and Chief, Geriatric Medicine

Director, Landon Center on Aging

Physician-Investigator, KCVA Healthcare System

Professional Background

Dr. Troen is a physician-scientist formally trained in both geriatrics and molecular biology, a Fellow of the American Geriatrics Society, and has been a VA physician-investigator for more than 35 years. He is presently the Chief of the Geriatrics Division and Director of the Landon Center on Aging .

Dr. Troen joined the University of Kansas Medical Center from the University at Buffalo Jacobs School of Medicine and Biomedical Sciences where he was Professor and Chief of the Division of Geriatrics and Palliative Medicine. Additionally, Dr. Troen served as a physician-investigator with the Western New York VA Healthcare System, and Chief of Geriatric Services at Erie County Medical Center and founded the Center of Excellence for Alzheimer’s Disease of Western New York and the Center for Successful Aging at the University at Buffalo.

He Co-Chaired the NIA/AGS conference on Osteoporosis and Soft Tissue (Muscle and Fat) Disorders and was honored in 2020 to receive a University at Buffalo Exceptional Scholar – Sustained Achievement Award.

Dr. Troen has several major foci of research: resilience, frailty, longevity/aging mechanisms, and osteoporosis, all of which result in great morbidity in older adults. He and his team have been elucidating what interventions can enhance physical performance, mobility, and cognition, particularly in those who are frail. Most recently, they have been investigating resilience in both pre-clinical and clinical models to understand the impacts on physical and cognitive function and the biological underpinnings, including epigenetics and metabolism. Their study on high intensity interval training was profiled in the New York Times. Dr. Troen is the Principal Investigator or Co-Investigator on biomedical translational grants from the NIH and VA, and previously from the NY State Department of Health and the State University of New York.
