Dr. Fangyu Liu is a Tenure Track Assistant Professor in the Department of Kinesiology and Health at Rutgers, The State University of New Jersey. Her research focuses on understanding the mechanisms of age-related conditions and declines, as well as how various interventions may impact these mechanisms. She applies causal inference methods to provide more rigorous causal evidence in observational studies.
