My Main Research Interests
My main research interests include the physical phenomena of seismic
wave propagation, the detection and understanding of the multitude
of seismic signals in seismograms, and the different strategies to
image and constrain the structure of the Earth interior.
In my most recent work, I designed several new techniques to improve weak-signal
detection and identification using individual seismic stations and one-component
or three-component station arrays.
My methods are based on new strategies, use the different seismic attributes and
are data-adaptive. The weak signal detection is important to increase our constraints
on the fine structure of the Earth. Automated signal detection/tracking/discrimination,
and travel time determination are related issues which catch much of my interests to
enable processing the increasing volume of good quality data.
Presently, I am also working on the localization and generation of
microseismic noise, seismic interferometry (monitoring and imaging), regional tomography and the polarization
and migration of reflected/converted waves.
