Research Experience

  • Feb. 2012-Present   Postdoctoral Research Associate, Geophysics Group, Los Alamos National Laboratory.
  • Aug. 2011- Present Foreshock Activities   Detected 12 times more foreshocks than listed in the catalog in the source region of the 1999 Düzce earthquake using the match-filter technique.
  • Aug. 2011-Feb. 2012   Postdoctoral Fellow, Dept. of Earth and Atmospheric Sciences, Georgia Institute of Technology.
  • May 2010-Present   Influence of Large Earthquakes on Regional Seismicity Rate: Identified seismicity rate changes in various regions in east Asia after the 2004 Sumatra, 2005 Nias and 2008 Wenchuan earthquakes.
  • May 2008-Present   Nonlinear Site Response: Performed a systematic survey of nonlinear site response vs. site conditions at 69 sites in Japan and 3 sites in California; Improved the geophysical/geological profiles for each site; Identified a refined threshold of soil nonlinearity, which is crucial in earthquake hazard mitigation and geotechnical/structural engineering.
  • Oct. 2009-Present   Dynamic Triggering: Identified and located the local seismicity triggered by stress perturbations of passing seismic waves in intraplate region and geothermal fields; Modeled a triggering mechanism based on friction failure for the dynamically triggered seismicity.
  • Jan. 2007-Present   Seismic Monitoring of Fault Zone Damage: Analyzed the spatial/temporal evolutions of the damage along the North Anatolian fault that ruptured during the 1999 %C4%B0zmit and Düzce earthquake sequences in Turkey; Developed an innovative sliding-window spectral ratio method in faults zone imaging and monitoring.
  • Aug. 2005-Aug. 2011   Research Assistant, Dept. of Earth and Atmospheric Sciences, Georgia Institute of Technology.
