Research Interests

I am interested in the continuum mechanics of planetary bodies, and the use of inverse theory to learn about their internal structure and composition. Most of my own work is on mathematical or computational problems in solid mechanics, but I am also involved in the practical application of these methods through a range of international collaborations.

My doctoral studies were done at the University of Oxford under the supervision of Prof. John Woodhouse. During this time I worked mostly on the theory of the Earth's free oscillations. Since then my focus has broadened to include a range of related problems including glacial isostatic adjustment, post-seismic deformation, body-tides, and orbital nutations. In all cases, my work seeks to improve both our ability to accurately model these processes, and to also develop useful tools for the solution of the associated inverse problems.

I have ongoing projects in the following areas:

  • Elastic wave propagation
  • Free oscillations of the Earth
  • Geophysical inverse problems
  • Glacial isostatic adjustment
  • Solid Earth tides
  • Rotational dynamics
