Research

I am interested in an integrated understanding of the physics and mechanics of finite earthquake source. With Professor Nadia Lapusta, we work on numerical simulations of fault behavior governed by laboratory-derived friction laws, incorporating long-term slow tectonic loading and short-bursting dynamic rupture. I focus on rheological complexities that produce a host of fault behavior to be observed seismically and geodetically. I also work on this problem from the observational prospective with Professor Mark Simons. We use Bayesian approach to sample for co-seismic/post-seismic slip models for recent megathrust earthquakes with the constraints from multiple data sets (GPS,InSAR, tsunami waveforms and etc.); from that we infer for the fault rheology and draw implications for earthquake physics. High-performance computing is an indispensable ingredient for both of these studies.
