Area(s) of Expertise
Geology: The petrology and tectonics of Proterozoic to Mesozoic mafic dike swarms of the Avalon terrane in southeastern New England; The nature and origin of chemical and mineralogic trends within individual dikes; The stratigraphy, petrology, and origin of the Columbia River Basalts and related silicic volcanics in southeast Oregon and adjacent portions of California, Nevada, and Idaho; The origins of magma pillow-like structures and variations in phenocryst concentrations in individual lavas of Steens Basalt.
I teach a wide variety of advanced and introductory undergraduate courses including igneous petrology and volcanology, structural geology, environmental geology, geology and land-use planning, and field geology. I have led extended field trips for undergraduate geology students to the Pacific Northwest, the Black Hills, and Iceland.
