Biosketch:
Rami Seliktar earned a Bachelor’s degree in Mechanical Engineering and a Master’s of Science degree in applied Mechanics, at the Technion, Israel Institute of Technology. His Doctoral degree in Bioengineering was earned at the University of Strathclyde, in Scotland, UK. Throughout his professional career, Dr. Seliktar held academic appointments in several institutions worldwide. Upon Graduation, The Scottish Home and Health Department awarded him an R&D grant for further development and testing of his PhD ideas in the area of Lower Limb Prosthetics and Human Performance. He was offered a position at the University of Strathclyde and remained on board for two more years, after which he decided to accept a faculty position in his Alma Matter; The Technion, IIT. He spent the subsequent nine years on the faculty at the Technion, climbed through the academic ranks and was awarded tenure. He was one the founding faculty members of The Julius Silver Institute of Biomedical Engineering in the Technion and was concurrently involved in consultation to the Israeli Department of Defense (Veterans Affairs), the National Center for Prosthetics and Orthotics and in 1973 he founded and directed the first Human Gait Analysis Laboratory in Israel, at the Loewenstein Rehabilitation Hospital. The Lab was a combined Research and clinical examination enterprise that during the ensuing years produced a substantial amount of scientific knowledge and clinical examination data. While serving as a faculty member at the Technion, Dr. Seliktar also spent a sabbatical leave at Texas A&M University and initiated his Joint academic and research work with Drexel University and Moss Rehabilitation Hospital in Philadelphia. Prof. Seliktar’s work in the Technion and the Loewenstein Rehabilitation Hospital had a substantial impact on the management and delivery of prosthetic limb services in Israel. In 1983 he resigned his position at the Technion and accepted a faculty position in Mechanical Engineering and Biomedical Engineering at Drexel University, where he is presently a full professor since 1987 and a Vice Director of the School of Biomedical Engineering Science and Health Systems.
During his 30 years tenure at Drexel University, Prof. Seliktar was instrumental in the foundation of the School of Biomedical Engineering, Science and Health Systems. He has done research on limb prosthetics, human performance, orthopedic and occupational biomechanics, assistive technology for persons with disabilities, and vehicle dynamics. His research has been funded by the NSF, NIH, the Robert Wood Johnson Foundation, the Easter Seal Foundation, NIDRR, Alfred I. duPont, the United Cerebral Palsy, some industrial enterprises, and medical institutions. He has published more than a 150 articles in scientific journals, book chapters, and conference proceedings and is serving on a number of international editorial boards.
Professor Seliktar is a Fellow of the American Institute of Medical and Biological Engineering.
