Ambient-noise imaging of sedimentary basins

My research focuses mainly in better understanding sedimentary basins (geometry, thickness) and the shallow Vs structure, characteristics which play a vital role in amplifying the strong ground shaking during earthquakes. The regions of interest have been the Los Angeles and Salt Lake City basins, home to millions of people and prone to elevated seismic risk. Moreover, our results from the Salt Lake City basin provide evidence for fault damage zone development at the East Bench segment of the Wasatch Fault, information crucial for source parameterization in ground motion simulations. 

Multi-parameter joint inversion of independent geophysical datasets

Another aspect of my research focuses on constructing and utilizing new tools to jointly invert independent geophysical datasets using innovative model parameterization, including inverting for more than one geophysical parameter at the same time. These methodologies include the joint inversion of surface wave phase velocity (isotropic and anisotropic), Rayleigh wave ellipticity, Receiver Functions and gravity.
