  • 2001: Ph.D., Geology, Boston University. Dissertation: Testing the viability and significance of magma mixing in continental arcs using the Sierra Nevada batholith, California, as an example.
  • 1992: B. A. Geology, Carleton College, Thesis: The Vourinos Complex as an Island Arc Accretion: Questioning the long held belief that ophiolite sequences were all formed at mid-ocean ridges.

Primitive (and evolved) basalts of the Poison Lake chain, southern Cascades:  Geochemical investigations of dozens of contemporaneous mantle-derived basalts erupted in a small area of the southern Cascades to determine the heterogeneity of the mantle beneath arcs.  Includes mapping, field work, major, trace- element and isotope (Sr, Nd, Pb, Os and Hf) geochemistry, electron microprobe studies of minerals and modeling of magma derivation and evolution.  Ideal for student research projects focused on one or more eruptions or relationships among eruptions.  Funded by National Science Foundation, UW Oshkosh and student grants from Sigma Xi, Geological Society of America, the Geology Department among others.  Students who are interested in pursuing a research project should

Magma mixing and the generation of continental crust in continental arcs:  Geochemical studies of plutonic (Sierra Nevada) and volcanic (Cascades) rocks in continental arcs to determine the processes that generate intermediate rock types that make up continental crust. Involves field work, mapping, major-, trace-element and isotopic studies of all rock types exposed in arcs.
