Human health has long been the subject of technological and scientific study and discovery. The life expectancy in the United States has increased by more than 50%, and the quality of life has been improved as a result of technical innovations in both science and engineering. Mechanics plays an integral role in Biomedical Sciences and Engineering, by providing a framework to understand and change how whole organisms, specific tissues, or individual cells interact with the environment. The Biomedical Engineering and Sciences group focuses on four primary areas: Orthopaedics, Cardiovascular disease, Biomaterials, and Rehabilitation engineering. The research is aimed at understanding and treating diseases associated with aging such as osteoporosis, arthritis, cardiovascular disease, and stroke. Orthopaedics is a major focus, with several research programs sponsored by the three major orthopaedic companies in nearby Warsaw, Indiana. A number of graduates of the program are presently employed in the orthopaedic industry.
