Sharing your wearable technology data can build a better world. There are hundreds of thousands of people using scientifically-valid wearable devices such as Garmin, Fitbit, and Apple smartwatches in order to track their activity and monitor their daily living. Using these data, we can better understand how people work, play, and commute. Everyone who uses a wearable device owns their own data, and each individual can decide how to share that information. Dr. Reed Ferber is a Professor with joint appointments across the Faculties of Kinesiology, Nursing, and the Cumming School of Medicine at the University of Calgary. He is the founder and director of the Running Injury Clinic and internationally recognized as a leading expert in biomechanics research using wearable technology. Currently, he leads a team of UCalgary researchers in the NSERC Wearable Technology Research and Collaboration (We-TRAC) CREATE Training Program to train the next generation of wearable technology experts. He is also an award-winning teacher and has been inducted into the Student’s Union Teaching Hall of Fame as well as being named a Killam Laureate after receiving the McCaig-Killam Teaching Award in 2020.
