My research interests include earthquake source mechanisms, energy budget of earthquakes and ground motion caused by dynamic earthquake ruptures.
Seismological observations bring a lot of information on the earthquake source and the structure of the Earth by comparing them to theoretical models, derived from solid mechanics. However, sometimes there are still discrepancies between the observations and theoretical models (e.g. high-frequency radiation in near-field), implying additional factors which conflict with the assumptions made in the models. My goal is to identify and quantify the factors using the state-of-the-art techniques (e.g. continuous observation of seismic wave velocity structure, physics-based dynamic earthquake rupture modeling), which enable us to better understand the source mechanisms, the overall energy budget and the consequent ground motion.

I am a computational and observational seismologist. My primary research interests include: 1) measuring both the elastic and an-elastic property of the Earth’s lithosphere/asthenosphere system 2) understanding the thermal evolution of the oceanic lithosphere and 3) modeling ground motions from potentially damaging earthquakes by using ambient seismic wave fields
