Research Overview

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. Stratigraphy provides unique insights into structural processes and past tectonic events that often cannot be gained from other disciplines. Integration of stratigraphic data with information from structural, geochronologic, paleontologic, isotopic, and geomorphic studies informs us about the dynamic interplay between surficial processes (erosion, transport, and deposition) and ancient fault systems that bound and create sedimentary basins. Stratigraphy also provides a useful tool for analyzing the history of slip, deformation, and related evolution of streams and geomorphology in active fault systems. I am working primarily in two areas: (1) Plio-Pleistocene evolution of basins in the Salton Trough and San Andreas fault system of southern California; and (2) Mesozoic stratigraphy and regional tectonics related to accretion and translation of oceanic terranes in central and eastern Oregon.

Current and Recent Research Projects:

Triassic-Jurassic collisional tectonics, Blue Mountains of NE Oregon

Late Cenozoic detachment faulting in the Western Salton Trough, southern California
