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, Lu-Hf isotope geochemistry, and optically stimulated luminescence; 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.
