     \ and faulting interact to shape Earth\u2019s surface. I study these phenomena\
     \ through geologic maps, laboratory techniques that measure the history of rocks\

   personal_statement: I came to the USGS as a Mendenhall Postdoctoral Fellow in
     2016 to study landscape evolution in the Southern Rocky Mountains and to help
     complete a facility for measuring the cooling histories of minerals as part
     of the Mineral Resources Program. In 2018 I transitioned to a job as a Research
     Geologist funded by the National Cooperative Geologic Mapping program, where
     I work now. In this capacity I conduct regional-scale geologic mapping and synthesis
     of Quaternary sedimentary deposits with the goal of ultimately establishing
     a seamlesss national-scale geologic map database that can aid in the characterization
     of geologic hazards and natural resources.  This work is currently focused in
     two regions, in Arkansas and in a large transect spanning the Intermountain
     West, for which I also serve as the lead of the surficial geologic working group.In
     addition to these roles I conduct research into the mechanisms of landscape
     evolution in an effort to better interpret the geologic record of natural hazards
     and past environmental change, focusing on two broad classifications of problems.  First,
     I seek to develop numerical and statistical models to refine geologic inferences
     made from geochronologic data and to quantify uncertainty in those interpretations.  Second,
     I try to understand the connection between earth surface processes, landscape
     form, and recent geologic deposits by developing numerical models that enable
     simulation of these phenomena.  In these efforts I am interested in developing
     approaches for characterizing landscape evolution through paired analysis of
     topographic and geologic map data.Prior to starting at the USGS I obtained my
     PhD from Stanford University in 2016, where I studied how sediment transport
     and erosion processes shaped hillslopes and river networks, and how some micro-climatic
     gradients enduced by aspect differences influenced these processes. In 2011
     I obtained my MSc from UC Santa Cruz, where I had also obtained my BS a few
     years earlier. It was at UC Santa Cruz that I first got excited about geologic
     mapping and where I developed an interest in using low-temperature thermochronology
     to study histories of faulting.
