Fulbright Graduate Research Scholar, 1993-1994
M.S., Geology, Washington State University, Pullman, Washington, December, 1989. Advisor: G.D. Webster
B.A., Geology, Humboldt State University, Arcata, California, August, 1983
Research Interests:
Middle Paleozoic depositional history and event stratigraphy, central Great Basin and Western
Europe; geologic record of bolide impacts; patterns and processes of the mid-Late Devonian
(F-F) mass extinction.
Research Projects:
Devonian to Early Carboniferous sequence and event stratigraphy, central Great Basin
and Western Europe
Geological record of bolide impact deposits, including the sedimentary geology, conodont
biostratigraphy, and depositional history of deep-water offshore and shallow-water
onshore deposits, early Late Devonian Alamo Impact Event, Nevada and Utah
Facies development, biotic turnover, and geochemistry of the F-F mass extinction
interval
