Faculty Profile


Brief description of current research:

I am primarily an epidemiologist who conducts both population- and clinically-based research. I specialize in the measurement of physical activity and physical fitness as they pertain to metabolic and musculoskeletal health outcomes.  Precise and unobtrusive measurements of physical activity are necessary to this area of study.  As such, I have been a leader in the field of accelerometry-derived physical activity measurement. I am an active fellow in the American College of Sports Medicine and the National Academy of Kinesiology.  I have recently completed 2 year service on the federal Dept Health and Human Service 2018 Physical Activity Guidelines for Americans Scientific Advisory Committee and am currently serving on the FitnessGram Scientific Advisory Committee.
