Document:
I investigate Quaternary earthquake records via field-based investigation, high-resolution topographic datasets (e.g., lidar, SfM), and geochronology. I serve as Intermountain West Coordinator for the U.S. Geological Survey’s Earthquake Hazard Program with a focus on characterizing seismic sources across the western United States. I have experience conducting field-based and remotely sensed research in the western and central U.S, the Caribbean, the Indo-Asia Collision, Central Europe, Pakistan, Australia, and New Zealand. Additionally, I advise USGS postdocs, I serve on PhD thesis committees at the Colorado School of Mines and University of Colorado, and I mentor undergraduate student research.
