Education and/or Training

Ph.D.	1994	University of Washington, Seattle WA	Geology
M.S.	1980	University of Washington, Seattle WA	Geology
A.B.	1976	University of California, Santa Cruz CA	Geology

Areas of Specialization and/or Research Interests

Metamorphic petrology and structural geology; tectonics; thermochronology.

Current research projects (task leader):
1) Investigation of the syngenetic massive sulfide (Pb-Zn-Cu) potential of the Nome Group, an extensive metamorphic unit on the Seward Peninsula, Alaska, and
2) Reconstruction of the Late Proterozoic and Paleozoic continental margin protolith of the Nome Group and its likely geologic context Results of these related investigations will be presented in a multi-chapter volume with papers on geology, stratigraphy, economic geology, stable and radiogenic isotope geochemistry, and U-Pb zircon geochronology and detrital geochronology
3) Late Proterozoic to Devonian paleogeograpy of Arctic Alaska (abstract presented at 2010 GSA Annual Meeting and Alaska Geological Society December luncheon)
