I'm a research fellow working with Dr. Emma Hill at the Earth Observatory of Singapore, where I use geodetic data to measure tectonic motion of the earth's surface — before, during and after earthquakes. These data help us to better understand the underlying tectonic processes in Southeast Asia and around the world, and allow us to provide key information about earthquake hazards to communities at risk.
My work involves new advances in InSAR processing, collection of GPS data around the region, and some novel inversion and numerical modeling techniques. See my research page for more.
Recent research highlights
Our work on the Main Himalayan Thrust in Nepal has been published in JGR. We showed that the pattern of interseismic coupling follows primary geologic features visible at the surface, indicating a long-lived and geometrically-controlled pattern of fault frictional behavior. We also showed that most previous geodetic models have significantly over-estimated the long-term slip rate on the fault, and our new estimate brings the predicted moment release rate more in line with paleoseismic estimates.
Our model showing the strong effect of the stress shadow during the interseismic period on shallow megathrusts has been published in GRL. We demonstrate that virtually all shallow megathrusts are highly coupled (kinematic coupling ratio above 0.8) whenever there is even a small area of down-dip locking.
We have significantly expanded our survey GPS network in Myanmar, with more than 110 sites now surveyed. Stay tuned for updates and follow the adventure on instagram.
