Sarah Keadle, PhD, MPH

Research Interests 

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.

Educational Background

Ph.D. Kinesiology, MPH Quantitative Methods

Current Projects

  • Activity Monitor Validation Study
  • Measuring the energy cost of driving
  • Validation of the ACT24, a mobile previous day recall tool
