Research Interests

• Kinematic modeling of earthquake sources; Determination of the spatio-temporal characteristics of earthquake rupture by i) inversion of full waveforms at regional and/or teleseismic distances, geodetic data, strong ground motion records and surface offset data and ii) inversion of relative source time functions
• Variability of strong ground motion due to source and site effects
• Near-fault effects on strong ground motion
• Simulation of strong ground motion using both deterministic (Empirical Green’s Functions) and stochastic approaches with emphasis on the incorporation of the finite-source and directivity effects
• Near real-time applications for the computation of earthquake source parameters (fast moment tensors) and shake maps for earthquakes in areas covered by sparse networks
• Moment tensor determination
• Study of non-linear site response during earthquakes
• Seismicity studies (relocation, determination of source parameters, seismotectonic implications)
