Where Am I Now?
I am currently a Mendenhall postdoc
on the Geologic Hazards Team
at the U.S. Geological Survey (USGS) Education
Ph.D., Earth and Planetary Sciences (Geophysics),
Harvard University, 2009
M.A., Earth and Planetary Sciences, Harvard University, 2006
B.S., Geophysics with Honors, California Institute of Technology
(Caltech), 2004
Academic Interests
I am interested in many different aspects of solid earth geophysics, including but not limited to:
earthquakes, glaciers, seismic imaging techniques, solid earth/atmosphere interactions, melting processes,
earth structure, mantle convection, and planetary formation/processes. My major
focus right now is on understanding short-timescale glacier physics and
microseism generation although I am working on a number of other projects as well.
