We study earthquakes using mainly seismology. We record and analyze seismograms (records of ground vibrations produced by earthquakes) to better understand the physics of earthquakes and the processes that control them. We work on large, damaging subduction plate boundary earthquakes to tiny local earthquakes. We are interested in better characterizing and understanding a broad spectrum of slip that we observe. In particular, we have pioneered work on slow earthquakes, a relatively new branch of earthquake science. Slow earthquakes are critical to understanding fault slip dynamics, earthquake nucleation and estimating earthquake hazard.

 

We develop new techniques to detect, locate and track slow earthquakes in high resolution. Typically, we conceive and design seismic experiments in an attempt to answer scientifically interesting questions, go to the field to install seismic stations, record new seismic data, analyze them, produce results and interpret them to come up with an answer. We specialize in seismic array techniques in various space and time scales. Our approach provides members of this group opportunity to do interesting science with options and flexibility to travel to distant places, explore nature and/or work in an office setting.
