Thrilled to share that my latest research has been published in IEEE Transactions on Biomedical Engineering!

Can analogue spine models behave physiologically?

We recently published 2 papers on this. They report our analogue spine's mechanical behaviour similar to living spines which we use to corroborate our in silico spine models and test spine implants in a controlled and validated environment.

L3-L4 fusion simulation on a lumbar spine phantom. We wanted to see if our 3D printed phantom could realistically simulate range of motion compensation in adjacent levels when fused. Results to come. #spine #biomechsky #biomechanics #mdsim #mcgill

CT of a stiffness-optimized #3Dprinted spine phantom for an upcoming study.

Today is the last day of classes for the "Intro to #MSK #biomechanics" course I'm teaching this semester. This has been such a privileged and rewarding experience for me. Got to #teach a very bright bunch of students. Looking forward to many more of these.!

This is brilliant!

I'm also interested in modeling muscle recruitment, particularly in spinal stabilization. Recently, we built a high-fidelity digital twin of this human torso, from scratch...with integrated flexible bodies, and the runtime is just under 10 secs!

Doing some HIL testing with actual hardware in Dec.

Something I've been recently interested in and is the natural next phase of the above model - introducing #IVD stiffness tuning and nonlinearly to be able to represent level-by-level stiffness variability and in a population.

The solution might be lattices!
