I study neotectonics on geodetic (years to decades) and geologic (thousands to hundreds of thousands of years) timescales. My research interests center around understanding how deformation is distributed spatially in plate boundary zones, and temporally through the seismic cycle associated with individual structures. For the shorter time scale, I use historical leveling and tide gauge observations as well as GPS and satellite altimetry to measure vertical deformation rates. My group is using high resolution observations of topography coupled with Quaternary dating methods to measure deformation rates averaged over multiple seismic cycles. Current geographic foci include the west coast of the U.S., the western Transverse Ranges, the Tien Shan mountains of central Asia, and locally in the Rio Grande Rift.
