I am a PhD candidate with the
Department of Earth and Space Sciences at the University of Washington,
in Seattle. I am advised by glaciologist Ian Joughin and collaborate with members from the
glaciology group, the seismology group and the
Polar Science Center
at the Applied Physics Lab.
My research primarily concerns the
transient mechanical response of ice sheets and glaciers to surface
meltwater. My field areas include Greenland and Antarctica. In both regions, I evaluate this
response using a synthesis of network-based seismic discrimination and meltwater modeling. I have provided
additional details of this work under my research tab.
In each component of my research, I use and develop quantitative methods
from convex set projections to quasilinearization of PDEs to facilitate rapid physical interpretation of observations.
My Greenland research is currently supported by the NESSF NASA fellowship program.
I graduated Magna Cum Laude from Washington State University in May 2004 with a B.S. in physics. My focus as an undergraduate was in shock wave propagation in novel alloys at the Institute for Shock Physics. I spent my first year at UW in the Applied Mathematics department where I obtained a Masters degree. In 2005 I entered the Geophysics program, where I have worked on several seismic field experiments, including the CAFE experiment, Ice Cliffs project in the Dry Valleys of Antarctica, and the Lakes Project in Greenland.
Aside from my research focus, I enjoy punk rock, time with valued friends and family, outdoor recreation, exercise, boxing, and recreational (safe) rifle shooting. Even on my days off, I also enjoy studying probability, mathematics, using MATLAB, doing forensic seismology, etc.
Additional Information and Tutorials
The Quick Links at the top of my site provide links concerning more details of my research, tutorial papers, presentations, and Matlab code to download:
- A poster summarizing a JGR-submitted paper on melt-triggered multiplet seismicity observed from Taylor Glacier, ANT.
- A manual for network-based counting, clustering, and correlation of seismic data using MATLAB.
- Some simple results on a method I developed generalizing matching pursuit to using a 'dictionary' of convex cones.
- A tutorial paper on nonlinear inversion (with a Geophysical example)
- An "Applied Math" Junkyard: derivations of mathematical tools with utility in data analysis. Keywords: projector matrices, inversion, probability, energy detectors, convex sets, constraint sets, array-based correlation.
- A tutorial paper on deriving the resonance frequencies of fluid filled glacial conduit, using an energy-based approach.
- Some old teaching materials on ESS 202, an Introduction to Earthquakes, taught here at the University of Washington.
Some materials are dated or old, but if you are sincerely interested in some of my work, do contact me.
