Research:
My main research goal is attempting to combine methods of geochemistry and petrology to answer questions about magmatic systems.
Currently my thesis is focusing on how and why megacrystic porphyries develop in silicic igneous rocks. I am conducting micromill transects of
decimeter scale orthoclase crystals to provide material for Sr and Pb isotopic analysis. By comparing the isotopic stratigraphy of megacrystals from a variety
of rock matrices and from different granitoids in the Sierra Nevada Batholith, isotopic trends can be evaluated to determine if crystal sizes are dependent
on disequilibrium processes or grow at a steady state.
