Research Interest


I am a Ph.D. student at Lamont Doherty Earth Observatory, Columbia University.

I am interested in everything the Earth has to say from its Heat Flow to its Gas Hydrates. However, my main passion revolves around subduction zones, the driver of plate tectonics.

In my Ph.D., I study elastic and inelastic deformation of upper plates in subduction zones linking this deformation to assessments of hazard.

Together with Prof. Roger Buck, I use thermomechanical models to simulate long-term slab dip reduction of subduction zones to explain short-term and widespread extensional deformation in the upper plate. Such deformation was observed following the Tōhoku earthquake and other events that produced larger than expected tsunamis. The extensional deformation has been linked to the larger than expected tsunamis that followed these events.

Together with Prof. Michael Steckler, I use geodetic data to quantify the total deformation of the Indo-Burma subduction zone in order to improve seismic hazard assessments for one of the most densely populated regions on earth.
