We correlate bone formation and resorption events in bone to the local mechanical environment at their location in order to understand how local mechanical signals drive bone (re)modelling responses.
Quantification of the mechanical regulation of bone adaptation shows age-related alterations (Razi et a., 2015)

Bone is able to adapt to the mechanical loads placed on it, by adding or removing matrix. We are interested in understanding how local mechanical signals within the bone regulate the local resorption and apposition of bone matrix. To achieve this, we use finite element techniques in combination with novel in vivo microCT image registration methods to correlate the local strain environment to formation and resorption events.
