Jeff Hausdorff, PhD, directs the Center for the Study of Movement Cognition, and Mobility at Tel Aviv Sourasky Medical Center. He leads a team of researchers working to better understand, evaluate and treat gait and balance changes associated with aging and disease. Dr. Hausdorff has studied gait, balance, motor control and brain function, with a special focus on gait variability, "fractal" physiology, and falls in older adults and patients with neurodegenerative disease such as Parkinson's disease. His work in this area has been funded by the National Institutes of Health and by private agencies and has been widely recognized. In 1996, Dr. Hausdorff received an award for his work on biodynamics from the Biomedical Engineering Society, and in 2013, he received the Gerontology Society of America's Excellence in Rehabilitation of Aging Persons Award. He received his bachelor's degree in engineering from The Cooper Union and graduate degrees in biomechanics and biomedical engineering from the Massachusetts Institute of Technology and Boston University.
