Biography

Education

  • Ph.D., University of California Santa Cruz
  • B.A., Pomona College

Courses Taught:

  • Mineralogy
  • Igneous & Metamorphic Petrology
  • Geochemistry
  • Research in Volcanology & Petrology
  • GIS & Remote Sensing
  • Planetary Geology
  • Plate Tectonics
  • Economic Geology

Research:

My research and teaching interests include all aspects of igneous petrology and volcanology. Since coming to Western my students and I have had many projects on the igneous rocks of the Gunnison Basin. These projects include:

  • the petrology and geochemistry of the old Precambrian island arc exposed south of town;
  • petrology and volcanic structures in the large Oligocene ash flow sheets from the San Juans exposed around Blue Mesa Reservoir;
  • petrology and volcanology of West Elk Volcano;
  • petrology and geochemistry of the Gunnison Laccolith cluster that makes up the high peaks north of town, including Crested Butte;
  • petrology and geochemistry of the Miocene flood basalts that makeup Flat Top, Red Mountain, Grand Mesa etc.;
  • petrology and geochemistry of the post ash-flow (Hinsdale) shoshonite and latite lavas exposed on the north slope of the San Juan volcanic field.
  • petrology and geochemistry of Tomichi Dome.
