I am interested in understanding earthquake and tsunami hazards in major subduction zones around the world, e.g., East Japan, Nankai Trough, Chile, Peru, Cascadia, Alaska, Sumatra, New Zealand, etc. One of the significant questions I hope to address is the tsunamigenic processes of shallow megathrust and outer wedge of the forearc, and the associated tsunami propagation and coastal inundation processes. I am also interested in the rheology and heterogeneity of deeper megathrusts and their implications for seismic behavior and coastal shaking.
