Biosketch:
Dr. Kurtz concurrently serves as a part-time Research Professor and director of the Implant Research Center at Drexel University’s School of Biomedical Engineering, Science, and Health Systems. Dr. Kurtz’ professional career has involved the evaluation of medical device technologies, from a combined analytical, experimental, and clinical perspective. His research activities have emphasized real-world clinical performance of medical devices, including orthopedic, spine, and cardiovascular implants, as assessed by human implant retrieval specimens and national health care databases; mechanical behavior of synthetic biomaterials; contact mechanics of artificial joints; and structural evaluation of bone-implant systems. Dr. Kurtz is active in many professional societies, including the American Academy of Orthopedic Surgeons, the Spine Arthroplasty Society, and the American Society for Testing and Materials. Dr. Kurtz has edited four books and written over 110 journal articles and 300 conference abstracts. He is the founding editor of two educational websites: the UHMWPE Lexicon (www.uhmwpe.org) and the Medical PEEK Lexicon (www.medicalpeek.org). He has recently completed the 2nd Edition of the UHMWPE Biomaterials Handbook.
