--------------
I am part of the Theoretical and Computational Seismology group headed by Jeroen Tromp. The Seismological Laboratory constitutes the geophysics option within the Division of Geological and Planetary Sciences at Caltech.

I was raised in Fairbanks, Alaska, and went to Carleton College and University of Oxford, prior to coming to Caltech.

Research interests:

Broadly speaking, I am interested in seismic tomography and seismic wave propagation. In many aspects, these topics go hand-in-hand: by using an accurate representaion of seismic wave propagation (the forward problem) in a seismic tomography study (the inverse problem), it should be possible to obtain accurate and well-resolved images of the Earth's interior. We are presently implementing adjoint methods into a 2D and 3D spectral-element method (SEM) code (see Seismic Tomography). Two relevant papers can be found here.

I am also working on a project with Mark Simons and Pablo Muse on a multi-resolution analysis of GPS data, and a project on subduction zone parameters with Mike Gurnis, Hiroo Kanamori, and Mark Simons.

Previous work:

Master's thesis, University of Oxford, Waves on a Spherical Membrane, here.
Faults and fault rock in the vicinity of Prince Rupert, British Columbia, here.
Tides and tidal sedimentation, here.
Mirages, here.

Here is an SS sensitivity kernel generated using a 2D SEM code.
This shows how an S-wave, travelling from star to box and bouncing off the surface,
samples the medium through which it travels.
See Seismic Tomography for more details (or our papers).

This spectacular USGS photo shows a massive landslide covering Black Rapids Glacier,
resulting from the M7.9 Denali Fault Earthquake (03 Nov 2002), central Alaska.
The fault zone runs parallel to this glacial valley in the Alaska Range.

My brother and I watched four coyotes tree this bobcat at Joshua Tree, just after sunrise.
