Research Interests

Biomechanics

  • Spinal Cord Injury
  • Aging Spine
  • Orthopaedic Implants

Current Research Work

  • Spinal Cord Injury: Our group uses experimental and computational approaches to determine whether the pattern of spinal column injury results in different types of spinal cord injury.  From a basic science perspective, we are searching for a biomechanical injury threshold for spinal cord tissue.   Clinically, this line of research is important in the assessment of different therapies for spinal cord injured individuals.  This is a highly interdisciplinary area of research that includes elements of neuroscience, molecular biology, and spine surgery.
  • Aging Spine: Over the past ten years, we have conducted a wide range of studies investigating the bone-implant interface in the aging spinal column.  Recently, we have developed a simplified two-dimensional model of the spine in an attempt to determine the efficacy of long implant constructs that are used in adult deformity.  This research has demonstrated the critical role of the posterior musculature in these patients.  Future research in this area will be to extend the model to three dimensions and to investigate in detail the spinal levels adjacent to the long implant constructs.
  • Orthopaedic Implants: Our group has investigated many biomechanical aspects of orthopaedic implant behaviour over the years, including hip and knee joint replacement devices, fracture fixation implants, and devices used in the spine.  Our most recent research in this area has addressed some design aspects of  total ankle replacement implants.
