Babak Ziaie, PhD has a broad background in design and development of biomedical devices and has extensive collaborations with physicians on numerous projects related to cancer, ophthalmology, neurology, and kinesiology. As PI or co-Investigator on many grants (NIH, National Science Foundation (NSF), industry), he has successfully managed the projects, collaborated with other researchers, and produced numerous peer-reviewed publications from each project. He is currently a Professor in the School of Electrical and Computer Engineering at Purdue University.

Shirley Rietdyk


Shirley Rietdyk, PhD is an expert in balance and mobility, and has been conducting research on balance and mobility for 27 years. Her overarching goal is to reduce falls in older adults, in order to reduce the personal and economic burdens associated with falls. She has successfully administered multiple research projects, collaborated with researchers in multiple fields, produced peer-reviewed publications, and has been funded through the National Science Foundation (NSF) and the National Institutes of Occupational Safety and Health (NIOSH). She is currently a Professor in the Department of Health and Kinesiology at Purdue University.

SmartGait LLC (established 2015) markets portable and reliable technologies for evaluating fall-risk in older adults and other balance-compromised individuals. The company is based in West Lafayette, Indiana and is a spin-off of interdisciplinary research conducted at Purdue University by Professors Shirley Rietdyk (Health and Kinesiology) and Babak Ziaie (Electrical and Computer Engineering).

Falls adversely impact health, result in substantive medical costs, and are the leading cause of accidental death in older adults. Falls result in chronic pain, functional impairment, disability, and nursing home admission. Identifying fall risk before a fall occurs is critical for timely deployment of preventive measures and to ensure that limited resources are allocated to the appropriate patients. To aid with this, SmartGait LLC is developing a portable system for gait and balance (sway) assessment. We are currently beta testing its flagship products, SmartGaitTM and SwayWatchTM in the local community. The systems provide quick and easy balance and gait assessments to large cohorts to alert users or caregivers about fall-risk and changing health, to take preventive action. The data collected is processed by the system to provide immediate feedback; additionally, the data is stored online on a HIPAA protected system, where it can be accessed by clients for detailed health reports and analysis.
