Caitlin Bailey, PhD, MS, is a Cancer Prevention Fellow in the Behavioral Research Program’s (BRP) Health Behaviors Research Branch (HBRB). In this role, she works with Dr. Dana Wolff-Hughes on projects to advance cancer-related risk factor assessment through the use of novel technologies and data science approaches. She is especially interested in research leveraging digital health technologies to improve the assessment of physical activity, sleep/circadian rhythm, nutrition, and obesity in cancer research.
Prior to joining BRP, Dr. Bailey received her doctorate in social and behavioral sciences in public health from The George Washington University. Her dissertation, which was supported by an F31 training grant, examined associations between the timing of physical activity and health outcomes in young adults. Her work received two Research Excellence Awards from the Society of Behavioral Medicine, including the Karen Calfas Award for physical activity research.
Prior to earning her PhD, Dr. Bailey was a Cancer Research Training Award (CRTA) fellow in the Division of Cancer Control and Population Sciences (DCCPS). As a CRTA fellow, Dr. Bailey worked with Dr. Linda Nebeling to support the activities of the Trans-NCI Obesity and Cancer Working Group. She also served as co-principal investigator of a DCCPS Collaborative Research Award for Fellows in Training (CRAFT)-funded study of time-restricted eating adherence. Dr. Bailey has a master’s degree in nutrition interventions, communication, and behavior change from Tufts University.
