I am interested in a broad range of seismological research, from shallow, high-resolution seismics targeting 10-100 m depth range to nuclear-explosion and earthquake seismology revealing the Earth's upper mantle structure to 500 - 1000 km.  In my work, I utilize computational data analysis and inversion techniques that help me reveal subtle properties of the structure of the Earth.  Much of this work is non-standard and requires development of sophisticated software tools.

Attenuation and seismological Q
  • Amazingly, many studies on the subject of Earth's attenuation may need to be critically reconsidered
  • We are currently analyzing:
    • Procedures for modeling and measuring attenuation;
    • Effect of Earth's structure in measuring attenuation; 
    • Causes of frequency-dependence of seismological Q and t*
    • General use of Q for describing attenuation;
    • Theory of visco-elasicity.
