Educational Background

PhD Mechanical Engineering, McGill University,

BEng (H) Mechanical Engineering, Minor: Aeronautical Engineering, McGill University,


My training is in mechanical engineering and biomechanics from McGill, and I also received training as a research associate/post-doctoral fellow in orthopaedic bioengineering at the University of California, San Francisco. My research interest is in multiscale mechanics (experimental and computational), mechanobiology, imaging and tissue engineering of musculoskeletal tissues. Contributions to bioengineering research have been made in a number of areas of the spine, knee and various tissues, related to intervertebral disc degeneration, scoliosis, low back pain, osteoporosis and osteoarthritis. My teaching is in the area of mechanics, biomechanics, structural engineering and finite element analysis.

Research has been funded by the Alberta Heritage Foundation for Medical Research (AHFMR), Alberta Innovates Health Solutions (AIHS), Alberta Innovates Technology Futures (AITF), Canada Research Chairs (CRC), Canadian Foundation for Innovation (CFI), Canadian Institutes of Health Research (CIHR), National Institutes of Health (NIH), Natural Sciences and Engineering Research Council (NSERC) and the Whitaker Foundation. 


Areas of Research

Orthopaedic Bioengineering and Multiscale Mechanobiology

Research aims to understand and quantify the mechanobiology transduction pathways which drive biological adaptation to mechanical stimulus in musculoskeletal tissues such as intervertebral disc, tendon, bone and cartilage, as well as in 3D stem cell seeded constructs for tissue engineering. In collaboration with biologists, engineers and surgeons, this research aims to provide a mechanistic understanding of mechanobiological factors in orthopaedic disorders, and provide the basic knowledge needed for the development of novel approaches to quantitative diagnostics and tissue engineered treatments.
