Current Research

My current research will focus on the Fish Lake Valley and Emigrant Peak fault zones in western Nevada. These two faults are located in the northern portion of the Eastern California Shear Zone where dextral shear is transferred to the Walker Lane Belt via the Mina deflection, a regional-scale releasing bend. Regional geologic evidence indicates that the ECSZ accounts for 20-25% of the total Pacific-North America relative plate motion. This is supported by geodetic data that show 11-13 mm/yr (or ~25%) of right lateral shear within the ECSZ. Despite the tectonic importance of the ECSZ, the space-time evolution of fault motions remains poorly understood. My future work will include new detailed geologic mapping and geochronologic investigations along the Fish Lake Valley and Emigrant Peak fault zones in order to constrain Quaternary dextral fault slip rates and improve our understanding of the space-time evolution of recent fault slip in the Eastern California Shear Zone and Walker Lane Belt.



Past Research

Master’s Research, Central Washington University, Ellensburg, WA, 2000-2003 Completed new detailed geologic mapping and cosmogenic radionuclide geochronologic investigations along the White Mountains fault zone in order to quantitatively constrain Quaternary dextral fault slip rates and to understand better the role of the White Mountains fault zone in accommodating right-lateral shear within the Eastern California Shear Zone (ECSZ).

Paleoceanographic Research Assistant, U.S. Geological Survey, Reston, VA, 1998-2000 Assisted in the preparation and separation of microfossil samples for carbon 14 dating, light stable isotope analyses, and quantitative paleontological analysis. Assisted in radiocarbon lab with the preparation of samples and operation of the graphitization line.

Senior Research, College of William and Mary, 1998 Evaluated the use of Cs-137 and Pb-210 as tools for measuring sedimentation rates in a brackish estuarine environment.
