Dr. Shawn M. O'Connor, MS, Ph.D. is an Assistant Professor at the San Diego State University. His research focuses on the biomechanics and control of locomotion and the development of movement health-sensing technologies. He aims to apply this knowledge toward rehabilitation strategies for improved balance and mobility with aging. He is interested in questions like: Why does balance ability worsen with age? How can we reduce the risk of falls in older adults while allowing them to stay active? To address these questions, he uses virtual reality and force fields to perturb subjects and assess walking function. He is also developing and testing next-generation muscle health, metabolic cost, and balance measurement systems for diagnosing the multifactorial causes of age-associated mobility decline.
