ASU Department of Geological Sciences, Tempe, AZ

Research Assistant
August 2003 – October 2006

·         Research the subsurface parameters and conduit dynamics that control the style and nature of explosive volcanic eruptions through quantitative modeling.


·         Develop and utilize a numerical model of the flow of magma through a conduit.


·         Wrote code to generate plots and created animations of results of numerical simulations of explosive eruptions.


·         Compare results of numerical models to petrologic data derived from pumice samples and video of volcanic eruption plumes in order to elucidate important subsurface processes that are not easily measured.


·         Preparing thesis research for journal submission.
