Research Interests

Dr. Michalek's research focuses on biomechanics of low back pain, with a particular focus on injury and repair of the intervertebral disc. This soft connective tissue structure is responsible for the dual roles of maintaining stability and connectivity of the spinal column while also allowing it to bend. The disc is composed of a complex, hierarchical fiber reinforced composite, which is extremely strong but slow to heal from injuries.

Current areas of investigation include growth and development of fibrous tissue structures, the mechanical consequences of tissue damage at a broad range of size scales, and evaluation of clinical therapeutic procedures with an eye towards minimizing invasiveness. This is accomplished through integration of mechanical testing, advanced digital imaging and analysis, and analytical modeling.
