Trans-D Bayesian fitting of spectroscopic data
This project aims at improving geochemical observables from Raman and Infrared spectroscopic data through the use of Trans-Dimentional Bayesian approaches used in Seismology.

Seismic tomography with irregular parameterization.
Global tomographic images correlate strongly with major tectonic features. The level of velocity variations is highly concentrated in the upper mantle and most globally recorded earthquakes occur in, or around, subducting slabs. This leads us to a new strategy in global tomography. We insert a-priori information by designing an irregular parameterisation which incorporates these observations.
The neighbourhood algorithm is a two-stage numerical procedure for non-linear geophysical inverse problems. It also has applications as a direct search technique for global optimization.
The Fast Marching Method (FMM) is a grid based numerical scheme for tracking the evolution of monotonically advancing interfaces via finite difference solution of the Eikonal equation.
