RESEARCH INTERESTS

Broadly speaking, my research focuses on analyzing the seismic recordings from earthquakes in order to better understand the different tectonic and geodynamic processes. Another objective of my research involves on seismic hazard assessment. Furthermore, I use the microseismic noises to study the the swells, landslides, etc... . In my work, I use different seismological methods including receiver functions, travel time tomography, surface wave dispersion, ambient noise, earthquake locations/relocations, source inversion, polarization computation and power spectral density analysis.
