Interests: Neotectonics, Structural and Quaternary geology

Current Research: Paleoseismology, conditional probabilities and seismic hazard of ground rupturing earthquakes. Slip rate, structure, kinematics, and evolution of faults and complex continental plate boundaries; currently working in Oregon, California, Central Asia (Kyrgyzstan), and SE Asia (Myanmar, Yunnan, and Thailand). Integrating modern geodesy, historical leveling and tidal records, and to map strain accumulation and relative sea level change; currently applied to Washington Coastal Resilience project on the Cascadia subduction zone.
