Research interests

My interests and research are in problems of theoretical mechanics in earth sciences and engineering involving the fields of seismology, tectonophysics, civil and environmental engineering, ocean sciences, and hydrology. Work on earthquake mechanics has focused on the stressing and strength of faults as relevant to the nucleation of earthquake-generating or aseismic rupture, its propagation, and the deformation of the adjacent environment. Studies of earth surface processes include subaerial and submarine landsliding and the hydrologic processes that may lead to such failure or that may otherwise shape the land or seafloor environments.
