Shirley Rietdyk

Professor, Health and Kinesiology

Dr. Shirley Rietdyk is Professor of Health and Kinesiology at Purdue University, with courtesy appointments in the Departments of Mechanical Engineering and Speech, Language and Hearing Sciences. She received her PhD from the University of Waterloo in Canada. Dr. Rietdyk examines the control of balance and locomotion in humans across the adult lifespan, with an emphasis on avoiding falls. She utilizes experimental and modeling approaches to discover how balance and mobility are achieved in complex environments. These factors are critical for maintaining independence and quality of life in the aging population. Knowledge of these factors informs the etiology of falls, leading to the development and assessment of fall-prevention interventions. She co-founded the tech startup, SmartGait LLC, to provide balance and gait assessments quickly and easily to large cohorts of people. Rietdyk is the author of 39 scientific papers and over 100 conference presentations. She received the New Investigator Award from the Canadian Society of Biomechanics, and the Exceptional Engagement Award from the Center for Aging and the Life Course at Purdue for her work in the community promoting balance and mobility in older adults.
