I am a Geology PhD candidate at the Mackay School of Earth Science and Engineering at the University of Nevada, Reno. I work for the Center of Neotectonics and Seismologic Laboratory of Nevada under the advisory of Dr. Steven Wesnousky. I use field-based mapping techniques along with high-resolution topographic datasets and modern dating techniques to understand lithospheric deformation of tectonically active regions. For my PhD, I am using examples of active faults and fault systems within the Walker Lane to gain insight on the distribution, rate, and structural style of deformation of an incipient transform plate boundary.

Here, I am utilizing a relatively new photogrammetric technique, known as Structure from Motion, to develop ultra high-resolution models (< 10 cm) of potentially offset geomorphic features along the northern section of the Pyramid Lake fault. The purpose of this study is to reevaluate the slip-rate and coseismic slip properties of the fault.
North American intraplate deformational studies have shown a relative northwest translation of the Sierran microplate, a stable ridged geologic province between the North American/Pacific plate boundary and the Walker Lane shear zone. Geodetic analysis of this motion has revealed measurable amounts of north-south contractional strain between latitudes ~400 and ~420 of northern California. As of yet, no geologic structures have been identified as accommodating active structures of this strain. My goal is to identify and characterize structures that are accommodating this strain.
The central portion of the Walker Lane experiences ~8 mm/yr of geodetically observed northwest directed transtensional dextral shear. This deformation is complex and accommodated by a combination of active north-south trending normal faults and counter clockwise block rotations focused in the west, and by a series northwest trending right-lateral strike slip faults to the east. Geodetic studies show that most of the horizontal dextral shear is focused in the east, within the region of strike slip faulting to the east. The geologically determined rates of slip on these faults are poorly constrained. I am using multiple high-resolution surface datasets along with modern dating techniques (cosmogenic nuclide and optically stimulated luminescence) to constrain the Quaternary slip rate across the Petrified Springs, Benton Springs, Gumdrop, and Indian Head faults. The sum of these rates will provide a platform for discussion of slip distribution within the central Walker Lane.
