Kathleen Sienko experienced microgravity for the first time when she was 21 years old. As part of a student project in engineering, she flew in a NASA training plane to test ways to detect structural damages to spacecraft. Although an eye injury precluded her initial dream of becoming an astronaut, she stayed closely involved in space-related research. She studied the physiological effects of long-duration spaceflight during summer internships at various NASA centers, and completed graduate studies in medical engineering and bioastronautics at MIT and Harvard. Now at the University of Michigan, Sienko investigates the use of sensory substitution technology in the design and development of prostheses and rehabilitation aids for people with impaired balance. One of her prototypes uses a cell phone to provide vibrational cues to a person when he or she begins to lose balance—helping the elderly, persons with vestibular deficits and post-flight astronauts maintain stable posture while standing or walking. In addition to pursuing balance-related research, Sienko and her students engineer easy-to-use, low-cost medical technologies for resource-limited settings. Below, Sienko answers the ScienceLives 10 Questions.
