General Interests and Background
I am interested in many aspects of volcanology. I grew up in western Washington state, with grand views of Mt Rainier, and other Cascade volcanoes. I have been fascinated by volcanoes and their activity since I was a child watching videos of Hawaiian volcanoes on television. My serious pursuit of the study of volcanology began as a freshman in college, when my professor shared an experience of his visit to the Big Island of Hawaii and his experience sampling an active pahoehoe lava flow. Ever since that story I have dedicated my elective study to volcanic activity, specifically basaltic volcanism.
College Career Research
During my college career I have worked on several volcano related projects. I have investigated the petrology of igneous rocks of Sawtell Peak, a 3,000-foot-high collection of Eocene volcanic rocks in the Centennial Mountains of Idaho, located less than 20 miles southwest of West Yellowstone, Wyoming. I have conducted further research on Snake River basalts as part of Project Hotspot. I performed detailed study of basalt core immediately after it was extracted from the subsurface drilling. Using X-ray diffractometry I examined the geothermal alteration of the Snake River basalts.
My doctoral research focuses on lava flow behavior. I use the Syracuse University Lava Project molten basalt to investigate several different aspects of lava flows including influences of the crust on final lava flow morphology, flow behavior over various substrates, and rapid runout lavas. My goal is to more fully understand why lavas take the shapes they do and relate that shape to emplacement conditions. This information can potentially give scientists the ability to infer eruption conditions for any lava flow in the solar system.
