Current Research and Scholarly InterestsI study the growth, tectonic evolution, and deformation of the continents. My research group undertakes field experiments in exemplary areas such as, currently, the Tibet plateau (formed by collision between Indian and Asia); the actively extending Basin-&-Range province of western North America (the Ruby Range Metamorphic Core Complex, NV, and the leaky transform beneath the Salton Trough, CA). We use active and passive seismic methods, electromagnetic recording, and all other available data!
Ph.D. Student in Geological Sciences
BioAs a Ph.D. student in the Mantle Processes Group led by Jessica Warren, my research revolves around the mantle. In particular, I study water in the mantle and how water affects mantle processes. I do field work in the Josephine Peridotite of southwestern Oregon, the mantle section of an ophiolite that formed 150 million years ago. My field site contains numerous, easily observed shear zones ranging from tens of centimeters to tens of meters in width, allowing me to study mantle deformation on a relatively fine scale. I compare the degree of deformation and deformation style with water content to learn more about water's effect on small-scale mantle flow. I also look at the relationship between water and other mantle properties.
