   personal_statement: My primary interests are in using mineralogy, crystal chemistry
     and rock textures to determine the origin and evolution of magmas erupting at
     Cascade volcanoes.  I am currently the USGS geologist who most versed in geology
     of the Lassen Volcanic Center and southernmost Cascades volcanoes and the geology
     of Mount St. Helens.  I interface with managers and staff at Lassen Volcanic
     National Park and Mount St. Helens National Volcanic Monument on geologic and
     interpretation issues in those parks.  I entered the USGS as a student field
     assistant in 1975 and have been employed there ever since.I am currently in
     the final stages of producing a geologic map of Mount St. Helens.  The field
     work is complete and I am writing the materials that will accompany the map.  My
     goal is to understand the complex eruptive history of Mount St. Helens as thoroughly
     as possible using stratigraphy and geochronology.  I and colleagues have added
     considerable detail to the geologic history framework produced by earlier USGS
     geologists.My work at Lassen is at a mature stage.  The geologic map of the
     Lassen Volcanic Center and vicinity describes the geology and eruptive history
     of the Lassen Volcanic Center and the many smaller volcanoes that surround it.  The
     basic geologic work at Lassen has been used to provide a framework for interpretation
     of the hydrothermal system and as basis for volcano hazards assessment of the
     region.  A variety of topical studies in collaboration with colleagues include
     geochronology, geochemistry, isotope geology, petrology, mineral chemistry,
     physical volcanology, geophysics, tectonics and hydrothermal systems.  Some
     of the geologic processes described at Lassen have guided work at other Cascades
     volcanoes and the arc as a whole.
