Short Biography

I earned my Ph.D. in 2009 from the Scripps Institution of Oceanography, then moved to Woods Hole, MA, for a Mendenhall Postdoctoral Fellowship. In 2013, I moved to Santa Cruz, CA, where I currently work as a Research Geophysicist at the USGS Pacific Coastal and Marine Science Center.

My Research: Offshore Hazards, Submarine Geomorphology and Active Tectonics

Image of Current Focus for My Research: Offshore Hazards, Submarine Geomorphology and Active Tectonics
  • Development and application of geophysical approaches to offshore earthquake (i.e., marine paleoseismology), landslide and tsunami hazard assesments

  • Understanding the interplay between tectonic, sedimentary, climatic processes along continental margins.

  • Combining basic and applied research to study the geomorphic development of continental margins, including substrate fluid flow
