Research Interests:

My research interests lie in using seismic tomography to infer tectonic structure in the crust and the dynamics of fault zones. I also investigate the effects of complex fault systems and background stress field on the rupture path during an earthquake using dynamic rupture simulations and generate broadband ground motion simulations for seismic hazard assessment.

Recent Projects:
  1. 3-D local earthquake tomography for high-quality travel time arrivals from aftershocks following the 2010 M7.0 Haiti earthquake.
  2. Broadband strong ground motion acceleration in southern Haiti for a hypothetical earthquake on the Enriquillo segment close to the capital city of Port-au-Prince using hybrid simulation approach that combines dynamic rupture simulations at low frequencies with stochastic simulations at high frequencies.
  3. Dynamic models of earthquake rupture along branch faults of the eastern San Gorgonio Pass region in CA using complex fault structure.
