   intro_statements:
   - My interests are in the physics of volcanoes; the processes that cause the changes
     that we measure and phenomena we see. This includes the mechanisms of magma
     transport, volcanic structure and magma storage, and during eruptions the transport
     of ash in the atmosphere. I use numerical methods, including artificial intelligence,
     to model data, and Bayesian methods to constrain the models with data.

   personal_statement: I have been a Geophysicist with the Cascades Volcano Observatory
     since 1996. My major accomplishments are as follows:Constructed a model for
     shallow water flow, modeled floods throughout western USShowed that a 2d shallow
     water model effectively modeled two millennial floods on the Verde River, Arizona,
     effectively verifying the three-dimensional variation of stage to give unique
     discharge of nearly 3200 cubic meters per second.  This discharge was verified
     by flow through a dam immediately downstream.Constructed a dambreak model for
     the Pakistan Army to mitigate the Haittian landslide dam that had just buried
     2 entire villages. Modeling determined how much to downcut the landslide to
     preserve infrastructure downstream. The cut was made and the resulting flow
     matched the prediction of my model. For this work Dan O'Connell and I received
     recognition from the Pakistan Army.Constructed a shallow flow model for debris
     flows and avalanches to model USGS flume data.Co-construction of Ash3d, an ash
     transport program, along with Hans Schwaiger (USGS) and Larry Mastin (USGS).
     Used Bayesian methods to refine forecasts of ash clouds.Used gravity and seismic
     data to quantify gravitational component, verify existing volcano-tectonic features,
     and illustrate the deep structure cradling magma and mush in the volcano.Past
