   personal_statement: "In my role at the U.S. Geological Survey, I study the supply\
     \ of materials important to society through materials flow analysis and mineral\
     \ resource assessment. Materials flow analysis provides a quantitative framework\
     \ for understanding how mineral resources are transformed into mineral commodities\
     \ and enter industrial supply chains through processes like primary production,\
     \ trade, manufacturing, end use, and recycling. Mineral resource assessment\
     \ involves characterizing mineral deposits and integrating geological, geochemical,\
     \ and geophysical datasets to better understand how and where minerals resources\
     \ are concentrated in the Earth.As a geologist, I am primarily interested in\
     \ the physical and chemical evolution of the Earth\u2019s crust. My research\
     \ on ancient and modern orogens focuses on the many processes that create and\
     \ modify continental crust including deformation, metamorphism, partial melting,\
     \ and magmatism. Interpreting the spatial and temporal patterns of these petrogenetic\
     \ processes requires a combination of field- and laboratory-based techniques\
     \ including detailed structural mapping, microstructural analysis, trace element\
     \ geochemistry, and accessory phase geochronology. To date, my projects have\
     \ ranged from characterizing strain in the Grenville basement complex of the\
     \ Virginia Blue Ridge, constraining the timescales of partial melting in the\
     \ Himalayan mid-crust through U-Th-Pb dating of syn-tectonic leucogranites,\
     \ evaluating rare earth phosphate mineralization mechanisms in Proterozoic gneisses\
     \ of eastern California, and assessing the timing and tempo of large igneous\
     \ provinces associated with catastrophic changes in Earth history."
