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 | |||
