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 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.

Current and Recent Research Projects:

Miocene-Pliocene Bouse Formation - Reconstructing the Origins of the Colorado River

San Andreas Fault Zone in the Coachella Valley, southern California

Late Miocene Coastal Sonora project

Plio-Pleistocene tectonics and paleoclimate, Fish Creek - Vallecito Basin, southern California

Older Projects, representative of my interests:

Triassic-Jurassic collisional tectonics, Blue Mountains of NE Oregon

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

Quaternary San Jacinto Fault Zone, southern California

Pliocene-Quaternary Loreto Basin, Baja California Sur, Mexico

Pleistocene to Holocene Laguna Salada, southern San Andreas fault system, northern Mexico

Miocene Detachment Basins, SE California and W Arizona

Jurassic Utah-Idaho Trough, U.S. western interior
