About Me Publications

I am now a computational geoscientist at Institute for Geophysics at University of Texas at Austin. My research interest is to integrate physics-based earthquake dynamic rupture and cycle models with various observations for a better seismic hazard assessment. Currently I am very interested in understanding the mechanics behind complex rupture segmentation and irregular recurrences in paleoearthquake record. I also work on applying dynamic rupture models to simulating high fequency ground motion.

Since January 2021, I start to work on geodynamic modeling and climate modeling. I feel there are a lot of good stuff that our earthquake community can borrow from theirs.
