Now at Washington University in St Louis.

[Previously: Postdoc (Seismology Group)].

My PhD research, at the University of Leeds, was aimed at investigating the fine structure of the Tonga-Kermadec subducted slab, using waveform and travel-time information from precursive seismic phases. Between 1994 and 1998 I was employed as a postdoctoral researcher at Harvard working principally on event location problems and improvements in modelling the uppermost mantle using regional phases. I am currently a research scientist at Washington University in St Louis, where I am involved in both the field work and data analysis of a project called Seismic Experiment in Patagonia and Antarctica (SEPA). I am also working on analysis of OBS data from Tonga-Kermadec.

This page was already out of date when I constructed it. It is composed of text and diagrams pulled together from various presentations I have made in the past and, apart from the ftp files of CMT-ISC associations, as such, does not necessarily reflect the most recent or comprehensive view of my research. In addition to this, some research I am doing is either at too incipient a stage to form a sufficiently coherent web page with, or is something I did some time ago, or have not yet presented; these works are therefore absent.

However, if you would like to know more about recent progress, have any questions, suggestions, or wish to get in contact with me for any reason, related to the research contained herein or elsewhere, I can be contacted in any of the following ways:
