My research focuses on understanding the structure of the oceanic lithosphere and asthenosphere using seismic waves. The oceanic lithosphere has a relatively shorter history compared to the cratonic lithosphere, as it is created and transported away from the spreading centers. However, previous observations have shown that a simple thermal model cannot fully explain the age-dependent variations observed in seafloor depth, heat flux, and the depth of the lithosphere-asthenosphere boundary (LAB). Various techniques have been employed to image these seismic structures, including (1) converted body waves (receiver functions), (2) ambient noise cross-correlations, and (3) two-plane wave tomography.
I am also interested in the excitation and propagation behaviors of ocean waves, such as infragravity waves, and their relationship to storm activity and Earth's hum excitation.
