Research interests:

My research uses sedimentology, stratigraphy, and geochronology to trace the transport of sediments across Earth’s surface to address problems related to the timing and mechanisms driving mountain belt erosion, non-marine sediment transport processes, and basin evolution over variable timescales. My research employs (1) field techniques: measuring stratigraphic sections, facies analysis, and geologic mapping; (2) analytical methods involving sediment provenance proxies using U-Pb geochronology and Hf isotope geochemistry; and (3) forward modeling approaches that incorporates digital elevation models and sediment provenance datasets to compare to the stratigraphic record. This multi-disciplinary approach provides insights into sediment transfer dynamics in terrestrial systems and resulting feedbacks and relationships with continental stratigraphy, which has implications for paleoclimate reconstructions, resource management, and paleogeography.

I am currently looking for students to work with at both the M.S. and Ph.D. levels. If you are interested in working in the Sed Tectonics Research group, please contact me by email.

Research projects include:
1) Using the sedimentary record to constrain subduction, magmatic, and mountain building processes during the Late Paleozoic Antler Orogeny across Nevada and Utah
2) Applying detailed stratigraphy and sedimentology to Neogene fluvial-megafan deposits to unravel tectonic and climate controls on fluvial transport processes in the Andes of Argentina
3) Understanding the feedbacks and relationships among Quaternary volcanism, climate, and sediment routing systems across the eastern Great Basin, USA
