MY RESEARCH AREA


    My research focus is on the subsurface imaging using geophysical survey. In particular, I am interested in detection subsurface velocity anomalies such like cavity and fault using geophysical survey.  I am also interested in programming to solve geophysical problems and visco-elastic seismic modeling using parrallel computing

    My current research has focused primarily on

    • Crosswell/VSP tomography , S-wave survey and Geophysical logging
    • Micro-seismic and Hydrofrac detection / Seismic data modeling using parallel clustering
    • Seismic modeling of long-distance for the global climate change
    • Seismic Modeling , Interpretation & visualization geophysical logging data
    • Geotechnical investigation and RemoteSensing signal processing
    • Geosciences software developing (Seismic SH-wave modeling program, Seismic logging, Fracture visualization module, Groundwater modeling, etc)
