Research Description:

The Berkeley Orthopaedic Biomechanics Laboratory, in the Department of Mechanical Engineering at UC Berkeley, was established in 1993 with three broad goals: 1) to educate students in performing independent, high-quality research in orthopaedic biomechanics; 2) to apply the principles of engineering mechanics to understand basic biological processes and mechanisms related to the structure and function of bone; and 3) to apply the principles of mechanical engineering to the design, analysis, and development of bone-prosthetic systems. Congruent with our emphasis on collaboration, our laboratory is closely associated with the medical school at UCSF (particularly the Department of Orthopaedic Surgery) with which we have a number of ongoing joint projects. This collaboration provides input from surgeons, radiologists, biologists and other bioengineers, and provides our students with first-hand experience in various clinical aspects of biomechanics.
