Interim Chair and Professor of Epidemiology
Finster Professor of Epidemiology and Anesthesiology
Dr. Li is working on projects aimed at understanding and controlling the epidemic of drug overdose and drugged driving, and uncovering the dynamics of injury risk and injury-disease interaction during the process of aging. Currently, he is the principal investigator of the Longitudinal Research on Aging Drivers project, or LongROAD. Launched by the AAA Foundation for Traffic Safety, LongROAD is a longitudinal multi-site study by researchers at Columbia University, University of Michigan, the Urban Institute, Bassett Research Institute, Johns Hopkins University, University of California San Diego, and University of Colorado Denver. Overall, the study will involve 3000 active drivers aged 65-79 years who will be followed over time through annual assessments and interviews in an attempt to answer five questions about older drivers:
• What are the main protective and risk factors of safe driving in older drivers?
• What medications are most strongly associated with driving performance and behavior?
• How do drivers self-regulate their driving behaviors to cope with physical and cognitive declines?
• What is the role of new vehicle technology and post-market vehicle adaptations in driving safety?
• What are the determinants and impacts of driving cessation (eg. on health and quality of life)?
To learn about their driving patterns, researchers will fit each driver’s vehicle with a GPS device. Data from this project will allow researchers to better understand the role of physical and cognitive functions, medical conditions, medications, and vehicle technologies in driving safety. Researchers will also examine how older drivers self-regulate to avoid difficult driving conditions, and the causes and consequences of driving cessation.
The study spans five sites in California, Colorado, Maryland, Michigan and New York and begins recruiting seniors 65-79 in 2015. Columbia Aging Center affiliated-faculty member Dr. Thelma Mielenz is a co-principal investigator of the New York site.

In addition to his research endeavors, Dr. Li also teaches Clinical Epidemiology at the Mailman School of Public Health, directs the clinical research program in postoperative care and critical care at the Department of Anesthesiology, College of Physicians and Surgeons, and currently serves at the interim chair of the department of Epidemiology at the Mailman School of Public Health. He received his MD from Beijing University and his DrPH from John Hopkins University.
