Patty S. Freedson


Assessment of physical activity with wearable sensors; development and validation of algorithms to characterize features of physical activity from wearable sensors; application of wearable sensor measures of activity and sedentary behavior in clinical populations.

Current Research
Her work focuses on development and validation of objective techniques to assess habitual physical activity and sedentary behavior in adults. and using these tools to quantify physical activity and sedentary behavior as outcomes in different research settings.

Her lab has been funded by a number of NIH grants. One grant examined new data processing methods to characterize physical activity using an accelerometer. A second grant was part of the NIH Genes and the Environment Initiative Exposure Biology Program, where she led a team of investigators in the development and validation of a multi-sensor wearable system to quantify physical activity behavior. The third grant examined how activity performed outside of purposeful exercise training impacted health outcome responsiveness to training. In 2007 she received a University of Massachusetts Outstanding Accomplishments in Research and Creative Activity Award. She is currently the president of the National Academy of Kinesiology, a former president of the New England Chapter of the American College of Sports Medicine and former vice-president of American College of Sports Medicine. She is a fellow of the Research Consortium, the American College of Sports Medicine, and the National Academy of Kinesiology.
