My research focuses on tectonic geomorphology, that is, the interactions of tectonics and surface processes. Specifically, my current research addresses potential feedbacks between climate, tectonics, sedimentation, and erosion. What can the products of these processes (e.g. sedimentary deposits and topography) tell us about the tectonic and climatic history of the region? Do higher precipitation rates drive more rapid exhumation? What factors control sediment accumulation or incision in intermontane basins within active orogens? To address these questions, I integrate a variety of techniques, including field mapping, standard stratigraphic techniques, U-Pb geochronology, magnetostratigraphy, detrital zircon provenance analysis, (U-Th)/He thermochronology, and GIS.
 
Projects
  • Interactions of climate, tectonics, and deposition in intermontane basins on the margin of the Puna Plateau, NW Argentina
  • Relationships between climate, tectonics, and exhumation across the Central Nepalese Himalaya as revealed by (U-Th)/He thermochronology
