Susan Marian Ellis (born 1965) is a geophysicist based in New Zealand, who specialises in modelling the geodynamics of the Earth's crust deformation, at different scales.
[3] Ellis's current work focuses on the influence of faulting on stresses in the crust, and how this is related to geological hazard and the tectonic settings in New Zealand.
[1] She subsequently completed her PhD in 1995 at Dalhousie University, where she examined the forces driving continental collision using numerical models, applied to Tibet and New Zealand.
Ellis has worked with and developed 2D and 3D numerical methods incorporating faults, inelastic rheology of the crust and mantle, and thermal and fluid evolution.
[8][9][10] Her work has focused on the influence of faulting on stresses in the crust, and the interplay between seismic and interseismic deformation, as applied to New Zealand tectonic settings.
