I am a Field Geologist interested in intracontinental tectonism in the western interior USA. The Late Cretaceous–Paleogene Laramide orogeny most fascinates me, and I have ancillary interests in post-12 Ma lower Colorado River transtension and post-Oligocene Rocky Mountain collapse. The methods I use include geologic mapping, structural analysis, thermochronology, basin analysis, and structural and mineralogical fault/fracture characterization. All aspects of geology intrigue me, and I enjoy immersing myself in new rocks, geologic settings, and methods.

Outreach, science communication, and teaching are also very important to me. I have taken part in field-based education for the Yellowstone Forever Institute, written geology articles for a small magazine in Bozeman, MT, and wrote and edited geologic signage and information as a Geoscientist-In-the-Park intern in Yellowstone.
