I am a Ph.D. candidate working with Kevin Stewart and Jason Barnes on tectonics and geomorphology. I am primarily interested in the spatial and temporal evolution of geologic structures and their geomorphic signature. My dissertation focuses on conceptual models of normal fault growth and the response of landscapes to active tectonics in extensional settings using apatite (U-Th)/He thermochronology and digital topographic analysis. My field site is primarily the U.S. Basin and Range region. My other interests include fractures and diagenesis, basin development, natural resources, and environmental geology.

My other, non-geologic interests include running and biking, cooking, brewing beer, climbing rocks, Obsidian, and the success of the Washington Redskins.
