Danny Brothers
I currently lead a project called "U.S. West Coast and Alaska Marine Geohazards" and I spend about 6-10 weeks per year at sea collecting marine geophysical data.
I received my Ph.D. 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. I grew up in Colorado and spent four years at CU Boulder for undergraduate studies in geophysics.
My research is focused on the following topics:
-
Development and application of geophysical approaches to offshore earthquake, landslide and tsunami hazard assessments
-
Marine paleoseismology
-
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
