Magnetic Resonance (MR) Elastography of the Intervertebral Disc

I am developing and validating MR Elastography as a method to non-invasively measure changes in disc mechanical properties during degeneration. Implementing this method will help to diagnose and monitor early stages  of disc degeneration.

Constitutive Modeling of the Intervertebral Disc

My objective is to develop and validate material models to describe and explain the mechanical behavior of disc tissues. These tissues are usually modeled using non-linear biphasic or triphasic theories.
