Patty Freedson is a Professor Emerita and former Chair of the Kinesiology at the University of Massachusetts/Amherst. She was a faculty member at UMass Amherst for 35 years. She is the founding Editor of the Journal for the Measurement of Physical Behaviour. Dr. Freedson has published over 200 papers and has lectured in the United States and abroad. Her NIH funded research focused on developing and validating methods for estimating physical activity and sedentary behavior from wearable accelerometers. The goal of her physical activity measurement research is to improve our understanding of physical activity dose for surveillance, intervention and determinants studies. Her original activity monitor calibration was published in 1998 and remains a tool used by researchers around the world to estimate physical activity using objective accelerometer sensors. She has also works with industry partners from the activity tracker market to improve the accuracy and precision of these popular consumer wearable devices.
