I am interested in a variety of topics regarding Earth's indigenous sources and its shallow and deep structure.  During my Ph.D., I developed new seismological approaches to study 3-D earthquake rupture properties and seismic structure of the near surface and mantle transition zone.  I also worked on mathematical analyses of seismic inverse problems for my M.Sc. project.  Currently at Caltech, I am working on constraining Earth’s rheology based on deformation after deep earthquakes, understanding spatiotemporal processes of underwater landslides, and improving site characterization in seismic hazard assessments.
