The Virginia Tech-Wake Forest University School of Biomedical Engineering & Sciences (SBES) is a joint graduate program formed in 2003 to bring together three prestigious academic institutions: the College of Engineering at Virginia Tech, the Wake Forest University School of Medicine, and the Regional Virginia-Maryland College of Veterinary Medicine. On August 11, 2014, Virginia Tech announced a new collaboration between SBES and the Engineering Science and Mechanics department to form the new Department of Biomedical Engineering and Mechanics. This department provides a strong foundation and a sturdy framework for the discovery, development, transfer, and implementation of new knowledge in the areas of mechanics of materials and material systems, fluid mechanics, dynamics and vibration, biomechanics, and computational methods. The department is fully committed to providing an environment for strong undergraduate and graduate education that emphasizes fundamental understanding rather than specialization, high-quality teaching, innovation, frontier-level research, and service to the professional mechanics community.
