Biography
General research statement: I investigate Quaternary earthquake records by combining field-based surficial mapping, high-resolution topographic datasets (e.g., LiDAR), and geochronology. I have experience conducting field-based and remotely sensed research in the western and central U.S, the Caribbean, the Indo-Asia Collision, the Dead Sea, Pakistan, and New Zealand. I lead the U.S. Geological Survey Earthquake Hazard Program’s Intermountain West Project, which is charged with characterizing seismic sources across the western United States. Additionally, I advise USGS postdocs, I serve on PhD thesis committees at the Colorado School of Mines, and I involve undergraduate students in research projects.
Active research projects
· Northern Walker Lane (California/Nevada) – Comparison of geologic and geodetic deformation rates in the northern Walker Lane. Use high-resolution airborne LiDAR (15-17 pts per sq-meter) to guide fault slip-rate studies, paleoseismic trenching investigations, and shallow seismic-reflection imaging.
· Intraplate earthquakes (Central & Eastern United States, Rhine Graben) – Constrain the timing of prehistoric earthquakes in stable continental regions using LiDAR. Focus on primary (fault scarps) and secondary (landslides) tectonic features. ,
· Altyn Tagh Fault (NW China/Tibet) - Constrain the slip history of the left-lateral Altyn Tagh fault through a combination of field-based topographic surveying, Quaternary mapping, and Quaternary Geochronology
· Slip history modeling - Developing slip-history modeling tools to construct fault slip chronologies in the western US, Asia, and New Zealand
· Paleoseismology - Constructing a paleoseismic slip records via traditional trenching approaches for the Enriquillo Garden Plantain fault (Haiti), Septentrional Fault (Dominican Republic), Kings Canyon fault (Nevada) and the Wasatch fault (Utah).
· USGS Earthquake Response - I am also involved with USGS post-earthquake responses, for example to the January 2010 and September 2013 earthquakes in Haiti and Pakistan, respectively.
My research interests include:
· rates of active strike-slip faulting
· fault slip-histories
· tectonic geomorphology
· Quaternary geochronology (e.g., radiocarbon, u-series dating of pedogenic carbonates, & terrestrial cosmogenic radionuclides)
