Current Research and Scholarly InterestsI am a fifth year Ph.D. student working with Steve Graham and a member of the Sedimentary Research Group. I am interested studying source-to-sink sediment transport patterns and basin development during the transition from convergent to transform margins. My current research focuses on the Cenozoic evolution of two systems: 1) the San Joaquin Basin and adjacent Salinian Block of Central California, USA; and 2) the Marlborough and Northern Canterbury Regions on the South Island of New Zealand.
My work in California uses detrital zircon U-Pb geochronology to characterize provenance changes in sedimentation due to the development of the San Andreas transform margin and consequential shutdown of the Cretaceous forearc system. These provenance signals can be used to re-evaluate key offsets points to better constrain the slip history of major strike-slip faults, and then applied to better understand the resulting interplay of local and regional sediment dispersal.
In New Zealand, my research employs a variety of methods, including characterizing outcrop stratigraphic architecture, sandstone petrology, conglomerate clast composition, and detrital zircon U-Pb geochronology to address questions of deep-water sediment transport patterns in response to the onset of uplift, local basement exhumation, and subsequent development of the oblique-slip Marlborough Fault System.
In addition, I have numerous ongoing collaborations with other research groups within and outside our department that include paleoclimate, paleoecology, thermochronology, and reservoir modeling studies.

I study the evolution of the Earth's crust by undertaking petrologic and geochemically-based research that is grounded with fieldwork. I co-direct the Stanford-USGS ion probe laboratory and develop geochronologic methods to constrain crystallization, metamorphic, and metasomatic histories of the middle to deep crust. Similarly, because heat flow characteristically attends mass transfer during crustal deformation, I employ 40Ar/39Ar and (U-Th)/He thermochronology to extract thermal history information from minerals to constrain the timing and magnitude of fault slip as well as erosional and tectonic denudation. Finally, I am heavily involved in provenance studies to constrain aspects of crustal deformation and erosion that are only preserved in the sedimentary record.
