Strong galaxy-galaxy lensing provides robust measurements of the total mass enclosed within the projected Einstein radius. Yet to study the detailed spatial distribution of this mass -- including its baryonic and dark mass components -- further modelling is required. To this end, I will present the results of spatially-resolved dynamical modelling of strong-lens galaxies, which can leverage the robust constraints from lensing analysis at the Einstein radius, while simultaneously providing spatial distributions of their constituent mass components. This analysis enables not only a direct comparison between different methods of measuring the dark mass on galactic scales, but also provides detailed insight into the build-up of the outer regions of strong lens galaxies -- a region of particular interest for lensing studies themselves.
