Erika Rees-Punia, PhD, MPH

Principal Scientist, Epidemiology and Behavioral Research


Erika Rees-Punia is a principal scientist in behavioral and epidemiology research. Her primary duties include conducting epidemiologic research and leading a physical activity intervention for cancer survivors.


Rees-Punia’s research focuses on the role of physical activity, sedentary behavior, and body composition in cancer prevention and cancer survivorship. She recently completed analyses examining the repeatability and comparative validity of the CPS-3 physical activity and sedentary behavior survey questions relative to other measures of activity. These analyses demonstrated that the CPS-3 survey questions reasonably capture physical activity and sedentary behaviors. She is now examining how different patterns, intensities, and timing of physical activity and sedentary behavior can prevent cancer.

Additionally, Rees-Punia works to promote active living among cancer survivors, with the goal of improving physical and cognitive function.
