I give lectures on time-dependent seismic hazards and stresses before, during, and after earthquakes.
Much of my past research has focused on the physics of deformation of mantle minerals
and aggregates at seismic frequencies and elevated pressures and temperatures. My past
research has also included the measurement and interpretation of seismic
attributes in the lithospheric mantle beneath mountain ranges and large strike-slip
faults. Currently, my research involves many aspects of probabilistic seismic hazard
analysis (PSHA), particularly for intraplate regions such as the central and eastern
United States, and includes time-dependent earthquake probabilities, ground motion
prediction equations, and earthquake clustering.
