Through my
post-undergraduate experiences I have developed a variety of interests in
structure, kinematics, and dynamics of active tectonic problems from the upper
mantle through the crust, particularly large-scale transform faults and
subduction zones. Most of my
activities center around quantitative assessment of structural and kinematic
tectonic models using many types of geophysical data.
October 2005 Seismic
Hazards of the Puget Lowland,
Postdoctoral research project, U. S. Geological Survey, Menlo Park, CA.
Planned
work:
* Create a structurally consistent 3-D model of the crustal thrust fault system in the Puget Lowland, based on reflectionseismic, tomographic, seismicity, gravity, magnetic, geologic, and geomophic data.
* Quantitatively asses the kinematics of existing 2-D models based on 3-D data set.
* Collect new gravity or magnetic data to fill in gaps in the model.
* Give a regional structural interpretation of the fault system including potential changes to known seismic hazard.
2004-present Southern
California GPS Network Development,
collaborative
projects
with Rick Bennett at the University of Arizona
* Assisting development of new projects that will attempt to constrain the temporal development of faults associated with the San Andreas fault zone.
* September, 2005: Installed new
campaign-style GPS network in Joshua Tree National Park (Joshua Tree
Integrative NetworkÑJOIGN) that will integrate with planned Plate Boundary
Observatory stations in the park.
2000-2005 Graduate
Research Project,
University of Arizona, Tucson, AZ.
* Assisted and lead field work in Chile and Argentina, maintaining PASSCAL broadband seismic network (2001).
* Created local seismic database at UA.
* Locating earthquakes and calculating
focal mechanisms with first arrivals.
* Analyzing located local and teleseismic earthquakes for evidence of anisotropy in the mantle and applying this to the broader problem of mantle flow in subduction zones.
2003 Seismology
Summer Intern, Lawrence
Livermore National
Laboratory, Livermore, CA.
* Learned the details of several seismic location techniques.
* Utilized scripting languages and
mathematica to develop a set of statistics for earthquake locations using the
GMEL earthquake relocation code.

clusters of earthquakes using the GMEL relative relocation code.
1998-2000 Geophysics
Intern, U. S. Geological
Survey, Menlo Park, CA.
* Lead and assisted field work collecting gravity data in Southern California and Nevada.
* Processed data into isostatic gravity
maps.
* Analyzed isostatic gravity and
aeromagnetic maps in conjunction with geologic data to estimate fault locations
and produce 2-D and 3-D models related to pull-apart basin development along
the San Jacinto fault, CA.
1997-1998 Senior
Thesis Research Project,
Greater Yellowstone Area,
Wyoming.
* Proposed and implemented a research project plan to study a sedimentary conglomerate deposit.
* Characterized stratigraphy of the
Crandall conglomerate, interpreted the paleotectonic setting.
1996-1997 Keck
Consortium Sophomore Research Project,
Williams College,
Massachusetts.
* Mapped surficial geology and made cross sections of an area of the Berkshire Mountains.
