Activties and Research Interests

The Tissue & Organ Mechanobiology (TOM) Group conducts research leading towards improving the current treatment methods for degenerative disorders and traumatic injuries of the spine. The group focuses its efforts on developing a better understanding of the interaction between living tissues and biomaterials, studying the influence of mechanical and physiological stimuli on tissue repair and development, and evaluating the potential for achieving a successful biological repair to an injury or to degeneration. We employ a variety of cell, tissue and organ level models in the study of normal and compromised intervertebral disc metabolism. A major initiative in our group is the development of appropriate three-dimensional scaffolds for the repair of annular and nucleus defects. Our first concepts for disc repair strategies have been evaluated in the laboratory and have proceeded through successful pre-clinical in vivo trials.
