My research combines the analysis of high-resolution digital elevation models (DEMs), field mapping, Quaternary geochronology, and computer modeling to quantify the tectonic and climatic controls on landscapes at active continental margins over Quaternary timescales. My present research focuses on understanding the kinematic and mechanical evolution of fault systems, such as the San Andreas. More specifically, I am interested in how deformation within the fault system is partitioned temporally and spatially. This information is important for characterizing the mechanical behavior and interactions of faults, evaluating contrasting hypotheses on whether mechanisms in the upper or lower crust govern long-term fluctuations in deformation rates and for earthquake recurrence models used in assessing seismic hazards.
