I work on modern and ancient convergent margins and the structures, rock assemblages, and regional relationships that characterize them. Most of my research concerns the Klamath Mountains, a composite oceanic superterrane that accreted to western North America in the Early Cretaceous. My current research focuses on Neoproterozoic Cyclomedusid fossils from the eastern Klamath Yreka terrane, and their significance for Proterozoic paleogeography and paleoclimate. These examples of the Ediacaran biota are similar to fossils from Australia, suggesting that the Neoproterozoic Yreka-Trinity composite terrane originated in the basin between Australia and Laurentia during the breakup of the supercontinent Rodinia. Recently published paleomagnetic data place these two terranes at 7° N latitude in the Neoproterozoic (580 Ma), and at 31° N or S latitude in the mid-Devonian (ca. 390 Ma).

Related research includes the structure and origin of ophiolites, mélanges, and accreted terranes in general. My participation in the Ocean Drilling Program, which provides modern analogs for these ancient rocks, has included the Peru Margin (Leg 112), the Chile Triple Junction (Leg 141), and the Costa Rica accretionary wedge (Leg 170). My students have worked on a wide variety of igneous, sedimentary, and metamorphic rock types and structures in the Klamath Mountains as well as in the Adirondacks of New York, the northern Rocky Mountains, and the North American Cordillera.
