Research interests

I am a seismologist broadly interested in tectonic, magmatic and near surface geological processes, and I address these problems with seismic tomography, monitoring, numerical modeling and seismic detection tools. My recent research focus on 1) developing and applying new techniques for shallow earth imaging, 2) monitoring volcanic and groundwater processes with the technique of ambient noise interferometry, 3) studying lithosphere deformation of continent and subduction zones by illuminating anisotropic properties of the Earth's interior and 4) using machine learning based approach for event detection. 

Keywords: observational seismology; ambient noise inteferometry; seismic monitoring; seismicity detection
