Interfacial Biomaterials/Biomechanics Laboratory

The Interfacial Biomaterials/Biomechanics Lab focuses on those healing phenomena that typically occur at a tissue material interface. While we must consider the biocompatibility of the material, we must also consider device function which is often dependent on the mechanics of the interface. For example, a simple fracture of the humerus is not difficult to treat non-operatively, but if the patient must be on crutches the mechanics are much different and the clinician may choose to plate the fracture. How big should the plate be? How stiff? Fractures of the pelvis are interesting because the loads on the pelvis are large, pelvis fractures can often be unstable, and fractures are often adjacent to nerves. How much hardware is needed to stabilize the fracture site to allow it to heal without affecting the spinal nerves? Similarly, a degenerated vertebral disc can be very painful, and treatment options are limited. What are some options for providing mechanical support without generating a response to the material that causes other maladies? These ideas are representative of our lab’s focus.
