My research is focused on field studies of tectonically active sedimentary basins, with the goal of understanding the complex tectonic, sedimentary, and geomorphic evolution of active regions. See also this summary. Stratigraphy provides unique insights into past environments and tectonic events that often cannot be gained from other disciplines. Integrated basin analysis informs us about the dynamic interplay between ancient fault systems that create sedimentary basins, and the surface processes that fill them with sediment. Stratigraphy also provides a useful tool for analyzing the complex evolution of streams and geomorphology in active fault zones. I am working primarily in two areas: (1) Miocene to Pleistocene evolution of basins along the San Andreas plate boundary system in southern California and NW Mexico; and (2) Mesozoic stratigraphy and regional tectonics related to accretion and translation of oceanic terranes in central and eastern Oregon.Link to some papers resulting from the following projects.
