Specialization

Seismic Source Studies, Strong Motion Seismology

Bio

Basic research interests are observing, analyzing and predicting strong motion from earthquakes. Following up on these interests involves dissecting the problem into more manageable pieces: collecting data, modeling the earthquake process itself, and understanding wave propagation in heterogeneous geological structures.
