I am a scientist at the Pacific Tsunami Warning Center (PTWC), part of the National Weather Service and NOAA,  where along with my colleagues we monitor the world's oceans 24/7 for tsunami hazards, develop new tsunami hazard detection techniques, and inform emergency managers and the public about our Center's operations and tsunami science.

Before joining the PTWC in 2006 I pursued graduate study and research in Geology and Geophysics in the School of Earth Science and Technology at the University of Hawaiʻi at Mānoa, earning a M.S. in these subjects in 1997 and a Ph.D. in 2005. This collaborative work was primarily on subduction zones, submarine volcanoes, and related phenomena using swath-mapping sonars (such as HAWAII MR1) and research submersibles (such as Alvin) to collect our data and samples.  For a list of my peer-reviewed publications please see this link or the one on the left.

About the logo: The image at the top of this page is inspired by my earthquake magnitude animation Perspective, the most popular video on my YouTube channel thanks to its positive reception at the S Factor workshop at the 2011 AGU Fall Meeting and subsequent sharing on several web sites. I also suspect that it may have inspired this poster (the timing is right, but I have no way to know for sure).
