Sarah Keadle, PhD, MPH
My research focuses on how different physical activities (e.g. exercise) and sedentary behaviors relate to chronic disease prevention. I conduct both observational studies to examine the link between these behaviors and health outcomes and intervention studies designed to reduce sitting and increase physical activity. I also have ongoing studies to determine how to accurately measure physical activity and sitting time using wearable sensors and previous day recalls.
