Elizabeth A. Fallon, PhD, MPH

Senior Scientist, Behavioral Research


As an expert in behavioral science, Elizabeth A. Fallon studies behavior change interventions and what motivates people to begin and maintain diet, physical activity, and weight management programs, with the goal of preventing cancer and helping cancer survivors thrive after diagnosis.


Changing physical activity, diet, or weight can be difficult, and few individuals are able to maintain their behavior changes over the long-term. Fallon’s research aims to uncover the individual, social, and environmental factors that lead to successful, long-term behavior changes, particularly among underserved groups and those at higher risk of chronic disease, such as cancer survivors, aging adults, rural communities, women, low income, and minority groups. 

Fallon’s current research uses data from the Cancer Prevention Studies, the Transition Study, and the Studies of Cancer Survivors to explore long-term patterns of physical activity and body mass index and the factors might influence these patterns. Previously, she validated the existence of the Termination Stage of the Transtheoretical Model for physical activity, which is a commonly used theoretical framework to explain and facilitate health behavior change. This research provides insight into the development of innovative interventions to improve the long-term maintenance of lifestyle behaviors.
