Research Interests

My research interests focus on the effects of rupture complexity and heterogeneities in Earth structure on the near-source seismic wavefield, and consequently, on the ground-motion properties relevant to earthquake engineering. Particularly, I have analyzed influence of directivity effect, supershear ruptures, fault roughness and medium scattering (due to random heterogeneities present in the earth structure) on ground-shaking and its variability. My research interests also involve understanding the physics behind reservoir induced seismicity and ground-shaking.
