My current research includes subsurface velocity estimation, both onshore and offshore, based on H/V spectral ratio analysis of ambient seismic noise and earthquakes. I am also interested in ambient noise characterization, surface wave tomography, and earthquake coda waves. The results are used for revealing very shallow to deep subsurface structures to understand the tectonics, geodynamics, and engineering geological aspects of a region.
