In this talk I will start with a brief introduction to the physics of glacial isostatic adjustment (GIA), focusing on the deformation of the solid Earth and how it can be modelled numerically. I will then describe the associated inverse problem whose aim is to infer the past evolution of ice sheets from observations of GIA . One approach to solving the inverse GIA problem is to use gradient-based optimization. Calculation of the required gradients can be computationally demanding, but I will show how this can be done very efficiently through an application of the so-called adjoint method. Finally, I will outline some future research plans which aim to incorporate ice-dynamics more fully into the GIA forward and inverse problems.
