Through research I aim to gain better understanding of natural and manmade structures by analyzing seismic waves.  Although the laterally averaged (i.e., 1D) Earth's seismic-velocity structure has been known accurately since the 1940s, subsurface is heterogeneity in 3D, even 4D, and understanding these heterogeneities is key to understanding Earth dynamics.  Among the topics I am interested in predicting ground motion caused by large earthquakes, understanding earthquake source physics, discerning the history of the Earth, anticipating volcanic eruptions, and imaging the distribution of natural resources (e.g., petroleum, mines, geothermal).  Seismic waves sample Earth's interior, and hence we can obtain information of the Earth in 3D.  Temporally repeating these measurements opens a window into the dynamics of the Earth. To extract such information, I use manmade seismic sources, earthquakes, microseismic, and natural and anthropogenic background noise (aka ambient seismic noise).
