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.
Imaging technologies of confocal and multi-photon microscopy, laser tweezers/scissors, optical coherence tomography, and ultra-high field magnetic resonance imaging are used in combination with uniquely designed multiscale loading devices, computational modeling and molecular biology for investigations across multiple scales in various musculoskeletal tissues.
Dr. Neil Duncan's background is in mechanical engineering with a specific interest and expertise in multiscale mechanics, mechanobiology, imaging and tissue engineering of musculoskeletal tissues. He holds a BEng (H) in mechanical engineering, with a minor in aeronautical engineering, and a PhD in mechanical engineering, both from McGill. He also received training as a research associate/post-doctoral fellow in bioengineering in the Department of Orthopaedic Surgery at the University of California, San Francisco. 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 and osteoarthritis.
His 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.
