Academic Interests

I am interested in many different aspects of solid earth geophysics, including but not limited to: earthquakes, glaciers, seismic imaging techniques, solid/fluid interactions, melting processes, earth structure, waves, mantle convection, planetary formation/processes, harnessing seismic noise, and earth surface processes. Some of my current projects include understanding how fault zone structure affects earthquake ground motions, creating new tomographic methods including with correlations, improving models of glacier and ice sheet motion, using non-traditional seismic methods to constrain geophysical phenomena, and modeling tsunamis.
