1. Glacial Isostatic Adjustment : Inferences on properties and processes in the upper mantle from 3D dynamical modeling
Abstract : Observations of glacial isostatic adjustment (GIA) offers a powerful window into the properties of the Earth's interior. Combined with dynamical modeling of the GIA process we can use the observations to infer properties such as the elastic structure of the lithosphere, the rheology of the mantle and changes in the stress conditions in the Earth.

2. Contributions of Satellite Geodesy to Post-Glacial Rebound Research
Abstract : Glacial Isostatic Adjustment (GIA) is a global and long-term process in the Earth, which began 21.5 millennia ago, according to many ice history modellers. One way to understand the processes of the Earth’s interior, the crustal deformation, and a key correction to estimate the climatological parameters is obtained by studying GIA. READ MORE

3. Developments in preconditioned iterative methods with application to glacial isostatic adjustment models
Abstract : This study examines the block lower-triangular preconditioner with element-wise Schur complement as the lower diagonal block applied on matrices arising from an application in geophysics. The element-wise Schur complement is a special approximation of the exact Schur complement that can be constructed in the finite element framework. READ MORE

4. Robust Preconditioners Based on the Finite Element Framework
Abstract : Robust preconditioners on block-triangular and block-factorized form for three types of linear systems of two-by-two block form are studied in this thesis. The first type of linear systems, which are dense, arise from a boundary element type of discretization of crack propagation problems. READ MORE

5. On modelling of postglacial gravity change
Abstract : Glacial isostatic adjustment (GIA) is the Earth's response to glacial-induced load variations on its surface. This phenomenon can today be observed in, for example, North America and Fennoscandia. READ MORE
