Current research interests

Bone-implant mechanics

bone implant drilling
Studying the interface mechanics established between metallic implants and bone issue is a core focus on the ORTHOtron lab. We are primarily interested in identifying mechanical factors related to implant fixation and loosening under physiologic loading in the spine.

Current project(s): Characterization of multi-axial fatigue of spinal implant loosening

Computational modelling

Computer model of knee cartilidge
We use finite element software to develop robust models to investigate the biomechanics of impact and injury to identify factors associated with injury risk and prevention.

Current Project(s):

  • Finite element modeling of spinal cord impact and injury risk
  • Finite element modeling of muscle activation in the cervical spine

Joint motion simulation

Joint motion detection setup
In vitro experimental investigations of human joint motion using state-of-the-art equipment is used to quantify tissue and joint mechanics to better understand normal, pathologic and repaired states.

Current project(s):

  • Simulation and measurement of physiologic spinal loading associated with daily activities of living

Computer-assisted orthopaedic surgery

computer rendering of spinal cord
Our group develops software and hardware tools for computer-assisted surgery, ranging from surgical simulation to 3D image-guided navigation.

Current project(s):

  • Virtual simulation of pedicle screw insertion
  • Visualization of spinal cord tractography

Additive manufacturing of surgical implants and instruments

Additive manufacturing machinery
Working with leaders in Multi-scale Additive Manufacturing at Waterloo, we are investigating next generation surgical implant and instrument designs.

Current project(s):

  • Optimization of interbody cage design and manufacturing
