Dr. Lans core research interest is in human aging at the population level, and can be extended into three interrelated areas: geriatric epidemiology, human longevity, and functional decline with aging. His research activity related to geriatric problems is to identify risk factors of elder hip fractures. To better understand the secret of long-lived persons, he is conducting the first centenarian study in Taiwan. Following his previous research on mobility limitations in older populations at the University of Cambridge, he has an ongoing project investigating the relationship between functional changes and subsequent health outcomes. Dr. Lan is also collaborating with researchers to analyze nationwide health survey data, including the National Health Interview Survey and the Taiwan Longitudinal Study of Aging.


Dr. Lan is a member of the Gerontological Society of American. He is a reviewer for the journals of Archives of Internal Medicine, Psychiatry Research, and The Gerontologist. He has published several articles over the past five years in the areas of geriatric epidemiology and preventive medicine.
